Any time data goes from one machine to another, temporary connectivity issues can arise, along
with potential for data loss, so OpenManage Network Manager accommodates this possibility too.
If a server is running for a long time (weeks) and the performance monitors have been frequently
enabled and disabled, some targets may not be polled because the appserver/medserver information
has become out of sync. It’s possible, but less likely, that polling and target information could be
out of sync even on standalone systems, where the application server also serves as a mediation
agent. This is why the following feature is also available on standalone systems.
You can schedule periodic resyncs of polling subscription and target information. The scheduled
item that runs this process is disabled by default, but if enabled it typically runs every 30 minutes.
You can also enable this item and schedule it more or less often than every 30 minutes.
If you enable this scheduled item, or run it a single time manually, then it ensures the mediation
agent has all of information it needs for polling. This includes the polling subscription information
associated with each active performance monitor and all active targets associated with each active
monitor.
