Running multiple instances of the JDBC Probe
You can run multiple instances of the probe on a single machine. This allows you to retrieve events from more than one event source.
When running multiple instances on a single host, you should specify unique values for the following properties so that the individual instances do not attempt to overwrite each others files:
- PidFile - this file stores the process ID of the probe.
- PropsFile - this is the properties file that the probe uses.
- DataBackupFile - this is the file the probe uses to record which events have already been retrieved.
You should also specify a different rules file for each instance
using the RulesFile property. For each probe
instance, you should customize the @Summary and @Identifier fields
of its rules file so that you can differentiate between the events
from the various data sources.
For example, suppose you have
name two probe instances: master1 and master2.
If you change the @Summary and @Identifier fields
in the rules file for master1 to the following values:
@Summary = "master 1 == " + $AlertName + ....
@Identifier = "master1" + $AlertID + ..and change
the @Summary and @Identifier fields
in the rules file for master2 to the following values:
@Summary = "master 2 == " + $AlertName + ....
@Identifier = "master2" + $AlertID + ..The probe
will precede all alarms acquired by master1 with master
1 and will precede alarms acquired by master2 with master
2.
