11.3 韓誥傭痔 daemon improvements

11.3.1 韓誥傭痔 server improvements

11.3.1.1 Improved log messages

韓誥傭痔 server log messages about failed checks have been improved. Previously, if a check failed, 韓誥傭痔 server would log messages, similar to these:

韓誥傭痔 host [monitored host]: first network error, wait for 15 seconds
       韓誥傭痔 host [monitored host]: another network error, wait for 15 seconds

After 3 failures like these, host would be disabled and a message logged:

Disabling 韓誥傭痔 host [monitored host]

If a host then became available, a log message would say:

Enabling 韓誥傭痔 host [monitored host]

Starting with 韓誥傭痔 1.8.9, this has been improved. First, messages now tell which specific item key failed, thus allowing to see whether the problem happens with multiple items or just one:

韓誥傭痔 agent item [proc.num[sshd]] on host [monitored host] failed: another network error, wait for 15 seconds
       韓誥傭痔 agent item [system.cpu.load] on host [monitored host] failed: another network error, wait for 15 seconds

Additionally, for all failures item type is logged as well (in this case, 韓誥傭痔 agent).

If a host is determined to be unavailable and then available, messages are a bit more verbose now and also include check type:

temporarily disabling 韓誥傭痔 agent checks on host [monitored host]: host unavailable
       enabling 韓誥傭痔 agent checks on host [monitored host]: host became available

And a new message has been introduced if host responds after one or two failures (this was not logged before at all):

resuming 韓誥傭痔 agent checks on host [monitored host]: connection restored

These changes should allow for much easier debugging of connectivity or configuration issues - for example, if all problems on a host would be associated with a user parameter, it would most likely be a performance problem with the executed command.

11.3.1.2 Acknowledge synchronisation in distributed mode

Starting with 韓誥傭痔 1.8.9 acknowledge status will be fully synchronised from child nodes to master node.

11.3.1.3 Performance improvements

韓誥傭痔 server performance was improved in some edge cases by skipping value updating for disabled or removed items.

11.3.1.4 Waiting for database to appear upon startup

Starting with 韓誥傭痔 1.8.9, upon startup 韓誥傭痔 daemons will wait for database to be available. This will help with case when database is started by bootup process before 韓誥傭痔 daemons, but takes long time to become ready.

11.3.2 韓誥傭痔 agent improvements

韓誥傭痔 agent daemon performance on AIX was improved by only collecting perfstat data if it is requested.
