if the agent connects to a satellite, not the master instance. If this node cannot connect to the parent node, choose n. The setup When evaluating Icinga2 versus other monitoring systems we recommend keeping these architectural advantages in mind. You should Request a signed certificate i(optional with the provided ticket number) on the master node. simple examples. Best practice is to run the database backend on a dedicated server/cluster and When being asked for the parent endpoint providing CSR auto-signing capabilities, 2) Modify each agent’s zones.conf file and add the host attribute to all parent satellites. You can also start with a single master shown here and later add Based on the master with agents use the nscp-local commands with >2 endpoints in a zone and a message routing loop. In order to make sure that all of your zone endpoints have the same state you need Since all events are replicated between both nodes, it is easier to just have one central database. Therefore disable the inclusion of the conf.d directory Select the check box to proceed. automated setup steps. you cannot monitor 3 or more cluster levels with it. In any case the constant is default value for the attribute and the direct configuration in the objects not supported. All nodes in the same zone load-balance the check execution. There are also a so-called passive checks which means that instead of Icinga running a check, an outside system would submit the result of some check to Icinga. On its own this can already be used to position multiple The NSClient++ REST API can be used to query metrics. required TLS certificates. on the master (see 'icinga2 ca list' and 'icinga2 ca sign --help' for details). additional security: The underlying protocol uses JSON-RPC event notifications exchanged by nodes. Both of them work the same way, are configured While you can and should use global-templates for your global configuration, director-global is reserved for use In order to keep things in sync between the two HA masters, This comes in handy if you have more than one failover_timeout attribute, but not lower than 60 seconds. more tips can be found on our community forums. Add this Hey guys, I tried to set up a test Icinga master server and endpoint check instance as a distributed monitoring architecture test. When Icinga establishes a TLS connection to another cluster instance it automatically uses the SNI extension The master schedules the checks, but does not run them. connection from the Icinga agent only. If you did not provide a setup ticket, you need to sign the certificate request on the master. you can leave the ticket question blank. The first thing you need learn about a distributed setup is the hierarchy of the single components. the command endpoint execution method. Upon successful installation of Icinga 2 , now start its services and enable them to â ¦ the IDO database. all services using the command endpoint mode. for accepting configuration commands. same zone. Create a new configuration directory on the master node: Add services using command endpoint checks: Validate the configuration and restart Icinga 2 on the master node icinga2-master1.localdomain. to the corresponding zones.conf entries for the endpoints. and must authenticate itself in a trusted way. Icinga 2 will only use one connection and apply service checks using the command endpoint execution method to them. zone. section where you can find detailed information on extending the setup. This documentation only covers the basics. If you want to restore a certificate you have removed, you can use ca restore. If you are eager to start fresh instead you might take a look into the tool (Puppet, Ansible, etc.). by Icinga Director. It creates dashboards with icinga2 data, giving you a frontend to monitoring information of your environment's systems. Defaults to disabled, as agents either are checked via command endpoint, or to get you started more easily. On a fresh installation the setup wizard guides you through the initial configuration. One possibility is to use a dedicated MySQL cluster VIP (external application cluster) Pass the following details to the node setup CLI command: The master_host parameter is deprecated and will be removed. endpoint objects, the agent will actively try to connect to the master node. You have learned the basics about command endpoint checks. Sync the host/service objects directly to the child node: Checks are executed locally. is to use the agent’s FQDN for all object names. Written from scratch, it builds on the success of Icinga 1 and deals with shortcomings inherited from Nagios as … In order to measure CPU load, you’ll need a running NSClient++ service. This is all done on the configuration master, and requires the scenario to be fully up and running. and handled by the Icinga cluster config sync itself. Icinga Director. i.e. In case of network failures or other problems, your monitoring might In order to use the api feature you need to enable it and restart Icinga 2. for the IdoMysqlConnection or Tip: Add --json to the CLI command to retrieve the details in JSON format. Icinga 2 is an open source monitoring tool used to monitor Servers, applications and Network equipment. to make sure that your cluster notifies you in case of failure. user (or the user Icinga 2 is running as). Tip: Best practice is to use a global zone Add the host and service objects you want to monitor. configuration can be rendered by the setup wizards. Now you need to restart the Icinga 2 service. Press Enter or choose y to establish a connection to the parent node. That way the master can verify that the request matches the previously trusted ticket ca list cannot be used as historical inventory. Use your preferred method to automate the certificate generation process. As this is only for testing purposes, it's okay to use localhost.localdomain. section where you can find detailed information on extending the setup. Icinga 2 is the monitoring server and requires Icinga Web 2 on top in your Icinga Stack. ApiListener object. and partner support channels: You can also extend the cluster tree depth to four levels e.g. No manual interaction necessary on the master node. backend, IDO database, used transports, etc.). The failover timeout can be set for the Choose one connection direction. Apply rules satellites where the connection information is needed as well. Vice versa, the This also requires a different value for nscp_api_host production and testing), Disparate sets of checks for entirely unrelated monitoring environments (e.g. (Hint: # icinga2 pki ticket --cn 'icinga2-agent1.localdomain'): No ticket was specified. Add the host object configuration for the icinga2-agent1.localdomain agent. Best practice is to run the database backend on a dedicated server/cluster and This ensures Icinga2 documentation clearly describes the master->satellite->client setup, but as of now everything can be configured using director module and top down approach, so you can easily monitor external remote networks that are not accessible from the master server.. icinga2 feature enable api). Command objects referenced by Host, Service, Notification objects. signing requests and responses might need some minutes to fully update the agent certificates. [root@pym ~]# icinga2 ca remove 5c31ca0e2269c10363a97e40e3f2b2cd56493f9194d5b1852541b835970da46e. in Icinga Web 2 or the REST API. Note: You can only have one so-called “config master” in a zone which stores no limitation for files and directories – best practice is to and run the node setup directly. To make sure that all involved nodes accept configuration and/or Certificate backends and web interfaces. You can add more parent nodes if necessary. We’ve seen them all in production Common examples are: Plugin scripts and binaries must not be synced, this is for Icinga 2 on both nodes. Icinga 2 copies the configuration into its zone config store in, Master node(s) check the connection to the agents, Optional: Add dependencies for the agent host to prevent unwanted notifications when agents are unreachable. refer to the automated setup section. Install the Icinga 2 package and setup 1) Don’t set the host attribute for the agent endpoints put into zones.d/satellite. This will be reflected Run the MSI-Installer package and follow the instructions shown in the screenshots. Each checkable host or service object is assigned to, Generate a new certificate authority (CA) in. The graphical installer offers to run the Icinga Agent setup wizard This is reasonable if you want to are not recommended with using the legacy HTTP API. You don’t necessarily need to add the agent endpoint/zone configuration objects to let them know about the new master/satellite node (zones.conf). and icinga2-satellite2.localdomain should not actively connect to the master If your nodes should send out notifications independently from any other nodes (this will cause If you are on v2.10 It was originally created as a forkof the Nagiossystem monitoring application in 2009. the command endpoint execution method on them. a zone for an agent/satellite and specify the parent zone, its zone members e.g. [Y/n]: Please specify the master/satellite connection information: Master/Satellite endpoint host (IP address or FQDN): 192.168.56.101, Master/Satellite endpoint port [5665]: 5665. using the host attribute, also for other endpoints in the same zone. Now click the ' Agent ' tab of the client1 host configuration. the command_endpoint attribute. Copy and move these certificates to the respective instances e.g. object with at least the actions/generate-ticket permission. zone and endpoint configuration for the agents. but changes the connection attributes - the first master already When needed you can add an additional global zone (the zones global-templates and director-global are added by default): Optionally enable the following settings: Verify the certificate from the master/satellite instance where this node should connect to. Copy the host’s certificate files and the public CA certificate to /var/lib/icinga2/certs: Ensure that proper permissions are set (replace icinga with the Icinga 2 daemon user): The CA public and private key are stored in the /var/lib/icinga2/ca directory. Set the local zone name to something else, if you are installing a satellite or secondary master instance. The Icinga 2 package on Windows already provides several plugins. existing. This creates an SSL- There is environment, including high-availability clustering and setup details information, e.g. for check execution. and the CA Proxy on all master, satellite and agent nodes. Add a new configuration file where all the health checks are defined. Note: The DB IDO HA feature can be disabled by setting the enable_ha attribute to false Icinga has its own rather extensive configuration language for defining the monitoring configuration. the /etc/icinga2/features-enabled/api.conf file and set This mode syncs the object configuration files within specified zones. The setup wizard fetches the parent node’s certificate and ask Again, only one side is required to establish the connection inside the HA zone. certificates need to be signed on the master first. the signing master: Setup wizards for agent/satellite nodes will ask you for this specific client ticket. By default, the following features provide advanced HA functionality: All instances within the same zone (e.g. In addition to that the --cn can optionally I used Icinga in school but I have been hired by a small MSP that would like to use it for monitoring Client networks. and commands (required for command endpoint mode). can be limited on the endpoint with the MaxConcurrentChecks constant defined in constants.conf. ping4). If you want to deploy plugin binaries, create In contrast to that, the satellite instances icinga2-satellite1.localdomain for keeping packages and scripts uptodate. infrastructure and applications). connected zones are working properly. note: If you rely on performance counter delta calculations such as The Endpoint object attribute log_duration can The DB IDO feature will try to determine which cluster endpoint is currently writing scenario we’ll now add a local nscp check querying a given performance counter. and pass its fingerprint as argument. Typical setups for MySQL clusters and store it as trusted-parent.crt. endpoint’s attribute on the master node already, we don’t want the agent to connect to the Automation tools like Puppet, Ansible, etc. and leave the IDO feature with enabled HA capabilities.
