opennms developers guide

Defaults to 1 when listing all resources, or to -1 (no limit) when listing a single resource. All available InfoPanelItem objects are sorted by the order. The request is limited to 10 items by default. This page is describes the RESTful interface for OpenNMS. To help with this effort, we have a wiki template which informs readers of articles that are tagged for migration to the official docs, or that have already been migrated. Read More WinRM in OpenNMS. /requisitions/{name}/nodes/{foreignId}/assets/{assetName}. If the focus contains elements which are not part of the graph, they are not shown. The same is for getting data from the API, even if it is possible to store v1 and v3 parameters in one definition block in the snmp-config.xml manually, the ReST API will only return the parameters which match the version. Obtain or modify the status of a set of monitored services based on a given search criteria, based on nodes, IP interfaces, Categories, or monitored services itself. Retrieve the last known state of all alarms which were active at the given time. Sets the readmail named {name} as the new default. This is the first line If you want to include just a specific segment of a large configuration file, you can assign tags that indicate to AsciiDoc the section that is to be included. If something not expected is received from the Service/DAO Layer when processing any HTTP request, like an exception, a 500 (INTERNAL_SERVER_ERROR) will be returned. It is possible to get some basic statistics on alarms, including the number of acknowledged alarms, total alarms, and the newest and oldest of acknowledged and unacknowledged alarms. Allows referencing the Vertex to an OpenNMS node identified by foreign source and foreign id. /nodes/{id}/ipinterfaces/{ipAddress}/services/{service}. guide-install/ module with the guide of how to install OpenNMS on different operating systems. The Topologies updates api are available under opennms/features/topologies. It is a simple API that allows for the submission and retrieval of Correlation Feedback. Attachments. Each graph or graph container can be persisted to the database using the org.opennms.netmgt.graph.api.persistence.GraphRepository. Apply the CORS filter to the '/rest/' path by removing the comments around the definition. Hierarchical Layout and Grid Layout. Defaults to 1 when listing all resources, or to -1 (no limit) when listing a single resource. Delete the service from the requisitioned interface with the given IP address, foreign ID and foreign source. In this example, just the service definition of the ICMP monitor should be included. Note that the notnull value causes the comparator to be ignored for eventAckTime, /events?eventAckTime=2008-07-28T04:41:30.530%2B12:00&id=100&comparator=gt&limit=20. The value of the guide attribute must be one of admin, development, install, or user. Get the interface with the given IP for the node with the specified foreign ID and foreign source name. The following are standard params which are available on most resources (noted below), integer, limiting the number of results. Add a user to the group, given a group name and username. When multiple Layers are used it is possible to navigate between them (navigate to option from vertex' context menu). Add a detector to the named foreign source. Performs an import/synchronize on the specified foreign source. Get the number of acknowledgements. Operating System / Environment. These domain objects don’t hold information on their own but provide only access to information that can be deducted from the underlying Generic Model and it’s properties. The Graph Service API provides a ReST API which is documented in detail here. (eg, GET /opennms/rest/stats/alarms/by-severity?severities=MAJOR,CRITICAL). Get the configured detectors for the foreign source named {name}. There are different versions of the interface (see below). The user can also search for all vertices and add it to focus. /ifservices?ipInterface.ipAddress=192.168.32.140. Log in ... NMS-9842: Documentation typo for /rest/ifservices on the developers guide; NMS-10027: The JMX-Cassandra service goes down for all the cluster when a single instance is down. All provided examples or code snippet may not fully work. This guide describes the requirements and how to get started with the development of the... 2. (note: the content between the + signs will be parsed); `command` is rendered as command (typically used for command-line or parts used in configuration files) /requisitions/{name}/nodes/{foreignId}/categories/{categoryName}. to get a list of configured scheduled outages. They can also contribute by submitting bug fixes or building new features like new collectors and monitors. Two vertices are connected by an Edge by the corresponding Port. Afterwards this is send to the OpenNMS Horizon REST API to create it: The topology-name is a unique identifier for the Topology. Please align your columns in the AsciiDoc source for better readability when editing in text view. It should describe installation scenarios and how to install OpenNMS on different platforms. All parameters can be set regardless the version. without the Base64 encoding part. In OpenNMS 1.11.0, some additional features are supported in the alarm ack API: Escalates an alarm. In some cases sections in the document also need to have ID’s; this depends on where they fit in the overall structure. Depends on RRA definitions. The following strategies are available: SPECIFIC Only Vertices which id match the graph’s property focus-ids are added to focus. the bytes transferred for the flows that fall outside of selected set. References the nth previous sample in the "sampleName" sample series. For example, the user adds C3 to focus, and the current layer is Layer 1, than the generated breadcrumb is as follows: Layer 1 > A1 > B3. (new in OpenNMS 14). In addition for each vertex which has connections to another layer, the user can select the navigate to option from the context menu of that vertex to navigate to the according layer. Mark the ICMP and HTTP services to be forced unmanaged for the nodes that belong to the category Production: Get a list of all KSC reports, this includes ID and label. To use a target id you follow this syntax: If you need to link to another document with your own link text, then follow this procedure: If you wish to use an external link, they are are added as: This will render in the output as: Link text here. Documentation incomplete see issue: NMS-7162. Retrieve the tree of resources rooted at the node with database ID, Retrieve the tree of resources rooted at the node with foreign-ID. Work In Progress This article is a work in progress, and as a result may change without notice. Resolve all vertices which match the concrete item. (Returns plaintext, rather than XML or JSON.). This includes the ID and node label. Secondary attribute that will be queried in the case the primary attribute does not exist. References the nth previous sample in the "sampleName" sample series. UPDATE message means that the topology message holds information about an OnmsTopologyRef Get the asset record associated with the given node. Afterwards this is send to the OpenNMS Horizon REST API to create it: The topology-name is a unique identifier for the Topology. There is nothing like having the code owner present and teaching, able to either answer any question you may have or do a bit of coding on the spot to help you out. CORS support for the REST interface (or any other part of the Web UI) can be enabled as follows: Open '$OPENNMS_HOME/jetty-webapps/opennms/WEB-INF/web.xml' for editing. Get the assets for the node with the given foreign ID and foreign source name. 😵 Please try reloading this page Help Create Join Login. This can be achieved by manually invoking the org.opennms.netmgt.graph.api.service.GraphContainerCache.invalidate(String containerId) method as the GraphContainerCache is exposed as an OSGi-service. On a successful request, the Email NBI will be notified about the configuration change. The value of the issue parameter must be a valid issue ID in the project issue tracker, and will become a live link. It is important that we maintain a level of consistency across all of our committers and the documentation they produce. Like normal expressions, expressions evaluated through this function will return a Java double value. Unless specific otherwise, all unit of time are expressed in milliseconds. Please note: If a namespace is added manually in order to use a XML tool to validate against the XSD (like xmllint) it won’t be preserved when OpenNMS updates that file. Integer value, which can be null, 1, 2, or 3. OpenNMS is a free and open-source enterprise grade network monitoring and network management platform. All of the scripts will be evaluated and the most severe status will be used for the vertex in the topology’s visualization. The following example shows a custom EdgeInfoPanelItemProvider. This means that when enabled, all alarms will be forwarded to the AMQP destination with strings as the message body. Performs an import/synchronize on the specified foreign source. Retrieve bits in and bits out metrics for a particular interface. E.g. Get the given service with the specified IP address, foreign ID, and foreign source name. guide-install/ module with the guide of how to install OpenNMS on different operating systems. When you identify an article in the OpenNMS wiki whose information should be migrated (either in its entirety, or just individual sections), use the following process. Enrichment is the process to enrich the view of the graph with additional information, usually used when the enriched data is expensive to load/calculate, e.g. Also is possible to set and get a Default Vertex. Retrieve basic information for the exporter nodes that have flows available, Retrieve detailed information about a specific exporter node, Retrieve traffic summary statistics for the top N applications or specific applications, Retrieve a list of the applications with flows, Retrieve time series metrics for the top N applications or specific applications, Retrieve traffic summary statistics for the top N conversations or specific conversations, Retrieve a list of the conversations with flows, Retrieve time series metrics for the top N conversations or specific conversations, Retrieve traffic summary statistics for the top N hosts or specific hosts, Retrieve time series metrics for the top N hosts or specific hosts. Instead if a custom icon should be used, each node must contain a iconKey property referencing an SVG element. Each Graph, Vertex or Edge have additional properties to define their nature in more detail. There’s a separate build that includes comments. However OpenNMS Horizon does not allow this. OnmsTopologyVertex implements OnmsTopologyRef and represents a vertex. If provided, returns only flow series that match the given conversation(s). /requisitions/{name}/import?rescanExisting=false. Get the IP interface for the given node and IP address. For example, a user adds C5 to focus, the generated breadcrumb is as follows: Layer 1 > A2 > B2. Current state: guide-install. Branches; develop; foundation To indicate that the supplied password uses the salted encryption algorithm rather than the older MD5 based algorithm, you need to pass an element named passwordSalt with text true after the password element (or key/value pairs if using JSON). Like users, groups have a simplified interface as well. Sets the level of the Vertex which is used by certain layout algorithms i.e. Read More. Example of valid parameter’s names are : default value is 4 hours ago). Delete the field from the requisition’s nodes asset with the given foreign ID and foreign source. The following strategies are available: SPECIFIC Only Vertices which id match the graph’s property focus-ids are added to focus. Creates or updates a -entry for IP address 10.1.1.1 in snmp-config.xml. By default you will not receive a challenge, so you must configure your ReST client library to send basic authentication proactively. All parameters can be set regardless the version. It uses the status of these nodes to calculate the status by determining the worst one. The Port is an element of the Topology because it belongs to an Edge and is the connection element. The default for offset is 0, and the default for limit is 10. It might be the title ends up in the last paragraph of the document. OpenNMS is an open source, enterprise-level, web-based, network monitoring system that can be used to monitor unlimited devices at a single instance. This can be achieved by simply using the Generic Graph Model and setting the according properties. For further details, see the minion-system-tests project on Github. Get the list of meta-data associated with this node filtered by the given context. /api/v2/ipinterfaces?_s=node.label==onms-prd-01, /api/v2/ipinterfaces?_s=ipAddress==192.168.32.140. The API allows to query any container and graph via ReST, but in most cases you should only query for a graph view. See Breadcrumbs for more information. both are set. notnull is handled similarly. /sched-outages/{outageName}/collectd/{package}. Target queue or topic. Always leave a blank line at the top of the documents section. […​] Note: the default offset is 0, the default limit is 10 results. These requests cannot be used to update or create new metrics. If you have a very long description, break at 120 characters and align the text to improve source readability. To do this head over to. Update the metadata of a group (eg, change the comments field). Get IP interfaces whose node are in the foreign source Servers: The /ipinterfaces ReST API is read-only. load node data or calculate the status. would return the 10 latest events inserted (probably, unless you’ve been messing with the id’s), would return the first 10 events associated with some node in location 'MINION'. readCommunity String if version is v1/v2c). Based on this template definition there exist a. This section is under development. This guide describes the requirements and the steps necessary in order to get started with the development of the OpenNMS project. This will also allow us to assign comments on a sentence in GitHub which will facilitate easier merging. Replacing the n samples before the start of the series with the first sample. While graphs aren’t technically available via ReST, you can parse some ReST variables to get enough data to pull a graph. If you have a very long description, break at 120 characters and align the text to improve source readability. A missing id in a mandatory place will cause the build to fail. If a user navigates from one vertex to a vertex in another layer, the view is switched to that layer and adds all vertices to focus, the source vertex pointed to. The default processor, the default-event-receiver-processor, expects the message bodies to contain XML strings which are it unmarshalls to events. protocol regex pattern, If provided, filters the results to only include conversations matching the given OpenNMS is used from people working different areas, so the documentation is split into the in following parts: Installation Guide: The audience is people who have to deploy OpenNMS in an organization. The actual Meta-Data of nodes, interfaces and services can be queried, added, modified or deleted via ReST endpoints. Requisitions are first POSTed and no provisioning (import/synchronize) operations are taken. The calculated breadcrumb is: > Multiple . Other than writing documentation, you can help out by providing comments on documentation, reviewing, suggesting improvements or reporting bugs. Get the entry for the given context and key associated with this service. If a resource is not modified during a PUT request, a NOT_MODIFIED will be returned. After the elements are ordered, they are put below the SearchBox and the Vertices in Focus list. Simply follow these instructions, they may vary depending on your Operating System. Note: the default offset is 0, the default limit is 10 results. Refers to nodes ids in the graph. To acknowledge or unacknowledge a notification, use the acks endpoint — see Acknowledgements. node id, See Breadcrumbs for more information. That’s: be a string made of the concatenation of: A Vaadin component which actually describes the custom component. By default, many browsers implement a same origin policy which prevents making requests to a resource, on an origin that’s different from the source origin. Report Begin: ${startDate} Report End: ${endDate}, — http://graphml.graphdrawing.org/primer/graphml-primer.html#Attributes, Retrieve the number of flows persisted in the last 4 hours, Retrieve traffic summary for top 10 applications in the last 4 hours, Retrieve traffic summary for top 10 conversations in the last 4 hours, Retrieve time series data for top 3 applications in the last 4 hours, Retrieve time series data for top 3 conversations in the last 4 hours, Verify classification engine (rule exists), Verify classification engine (no rule exists), Retrieve CPU counter metrics over the last 2 hours for node 1. In version 1 only a few attributes defined in snmp-config.xsd are supported. If no focus is provided when requesting the view, the default focus is applied. It allows packages to register Maven Repositories, Karaf Feature Repositories and Karaf Features to Boot by overlaying additional files, avoiding modifying any of the existing files.
