Hi,
I can't see in the history what ODBC tools you are using to do the
monitoring or how the monitor is checking the connection.
But if that is proving unreliable or providing false positives sometimes
perhaps you need to go the other way and have the LPAR provide a heartbeat
on whatever frequency you are wanting to check. The heartbeat could be a
timestamp written to a file either on the lpar or on an external device or
a data queue or a web service call or whatever you like.
But if the problem is the monitoring machine has a network problem and
that is the only monitoring tool then that is a problem!

Subject: Re: IBM i Monitoring utility
I am trying to distinguish between the host is down or lost the connection
to the host. In the latter situation, our monitoring tool will post an
alert the host is down, That eventually ends up as a SMS message to the
help desk who call the techs. If they then logon and see the host is not
down, they are not happy :-(
I did some research on this and it seems we could use the HMC. It has a
REST API which we can ingest from our monitoring tool and feed the data
into the same date pipeline we now get from ingesting QSYSPOPR. It doesn't
look too hard but this was not an options our team that manages our
corporate wide monitoring infrastructure since they don't know anything
about IBMi!
