Upgrading Distributed Monitoring

General
1

Dear Forum.

I have a case where i have over 20 sites and one master, at our owne datacenter.
We are currently running 1.5.0p16 and would like to upgrade to the 1.6.0p8

Would it be possible to upgrade only the master site? or do we need to take all sites offline to upgrade them?

And also. The whay we communicate with these sites is via a SSHTunnel, and adding them as Livestatus proxeys. With this we get a lot of connection issues.

What would be a better way of getting the data back to the master site?

You need to upgrade them all at once, if you use distributed WATO, as the configuration has completely changed.

Are you using SSHTunnel to encrypt the Livestatus traffic? This is now built into 1.6.

Yes. What would be the best way to replace the SSHTunnels? Would we just specify the master public ip?

Hi bjerre,

please see 2.3 in https://checkmk.com/cms_distributed_monitoring.html

Steps:

  • upgrade all slaves and the master
  • turn on livestatus encryption on the slaves (omd config SITENAME)
  • configure the slave connections on the master to use encryption
  • accept the certificate once per connection
  • happy monitoring
