Context
Moab and the Insight daemon gracefully handle disconnects or restarts. If you restart Moab, you do not have to restart Insight. To handle instances of disconnect, or downtime, Moab stores all data it attempts to send to Insight in memory and on disk. Once Moab generates enough data to meet the maximum storage size, it begins to delete the oldest data and make room for the new data. The size of the data on the disk is two times the maximum storage size. By default, the maximum storage size is 1 GB with 2 GB max on disk. You can customize the storage size for your unique environment.
To configure reliable message delivery
- Open the Moab configuration file on the Moab head node and set the INSIGHTSTORESIZE and INSIGHTSTOREDIR configuration parameters. See Moab Parameters in Moab Workload Manager for parameter information.
[moab]$ vi /opt/etc/moab
...
INSIGHTSTORESIZE 2048 # 2 GB store size with 4 GB on disk
INSIGHTSTOREDIR /tmp/insight_store
...
If INSIGHTSTOREDIR is a relative path, the Moab home directory is prepended to it. It uses the given path if it is an absolute path.
- Restart Moab in order for the new configuration parameters to take effect.
