AIX monitoring
 |
AIX monitoring uses these datasources:
- HMC
- CMC
- OS agent
The OS agent enhances monitoring about additional metrics which are available only from the operating system.
The agent supports AIX 5.3+ and even VIO servers.
If even the HMC is being monitored, then the AIX OS agent data is mapped to the server tree under that LPAR.
OS agent implementation
There is XorMon daemon listening on the host where XorMon server is running on port 8162.Each LPAR has a Perl-based agent installed. This agent is started every minute from the crontab and it collects performance, configuration and log data.
The agent contacts the XorMon server every 10-15 minutes and sends all locally stored data for that period.
OS agent prerequisites
- Perl interpreter. All Unix/Linux systems contain Perl in basic installation.
- It may run under any user account, it does not need any special privileges in the OS.
- Opened TCP communication between each LPAR and XorMon server on port 8162.
- Connections are initiated from the monitored AIX host only.
