Infrastructure Data Collector Clustering for High Availability
Infrastructure Data Collector supports active/passive clustering for high availability scenarios. In this case, one of the Infrastructure Data Collector instances is marked as active, and the other one as passive. The passive Infrastructure Data Collector node is stopped, and should be started when the active node goes down.
Note:Infrastructure Data Collector does not support automatic switching from active to passive cluster node. This must be done by the user.
To configure
Infrastructure Data Collector clustering for high availability
1. Install two Infrastructure Data Collector instances.
2. Start the two instances.
3. In My webMethods, configure the two Infrastructure Data Collector instances.
Important:
Make sure you register the two instances with the same collector name under Collector Settings for Infrastructure Data Collector.
For more information about defining collector settings for Infrastructure Data Collector, see Configuring BAM.
4. Shut down the two Infrastructure Data Collector instances.
5. Start the active Infrastructure Data Collector instance. It discovers assets and monitors components, as configured.
6. To test the clustering scenario, shut down the active Infrastructure Data Collector node, and start the passive one. The monitoring should continue as usual.
Note:
If you are monitoring SNMP agents, you have to re-discover all of them on the passive Infrastructure Data Collector node.
