[Check_mk (english)] Smart ping, availability reports and host graphs

Archive checkmk-en

Hi Antti,

please try executing "cmk -R" as siteuser and check if the
availability is working after that.

If it's still not working I think that's a support case...

BTW: do you get host and service events displayed using the "events"
button at top of a view?

Regards,
Marcel

Hi, perhaps I was not clear. The problem is that the historical data copied over from Nagios is correct and shows up fine even with CMC, but no new data is visible.

The availability for the period where CMC is running is showing up as NA.

We don't need ping times, but we do need the availability information.

Hi Antti,

1) The CMC writes its history files in another place than Nagios (but
is able to read the later). You can copy all history files from Nagios
location to the CMC location and restart the core:

cp ~/var/nagios/archive/* ~/var/check_mk/core/archive/
cmk -R

2) With smartping no performance data is written. That's why the host
graphs are empty from the time of migration. But the (old) data is not
removed and so the CMC finds the xml and rrd files which leds to
showing the graphs/graph-icons in the GUI.

HTH,
Marcel

Hi,

  for testing, we just migrated one of our monitoring sites from Nagios to CMC. Two things...

  1) Availability reports. The hosts show N/A for availability ever since we switched to CMC. Is this normal? How can we get accurate availability reports for hosts or is it something that will start working later when enough data is gathered (I tried omd restart to check if status would be "flushed" by that).

  2) I know that to monitor ping times, you need to set up an explicit "PING" check. However, if I don't do that, what's the "host graph" for? So far it's been empty. The migration guide at https://mathias-kettner.com/cms_cmc_migration.html only mentions that "after a conversion from a Nagios core the host checks at first provide no performance data". What does this "at first" even mean?
