RE: [hobbit] xymon ready to replace bb?


Grmph,

you're right,  one place for all is the best solution ..

Me for myself,

 i switch from side to side ... and would prefer on central Side, too !

... by the way, the wiki-side from TJ is very well and comprehensive ...

there will be a lot of things to merge into the "offical" Xymonton ...

While I don't want to minimize TJ's work, I don't believe people realize that Xymonton, the Xymon repository for custom tests, is actually built on top of Dokuwiki.
This is exactly the type of information the tutorials page was meant to 
capture.  It might be helpful if we had a one stop shop for all things Xymon instead of going one place for scripts and another for docs.


Just my 2 cents (not that I have any vested interest in this ;-) )

Hi, Harald !


Xymon with Linux HA cluster with DRBD


did you make some doku's or notes for it ?

.. there is an old thread from Februar but unfortunatley no notes till this moment ...

http://www.hswn.dk/hobbiton/2009/02/msg00146.html

But there is already some place for it :-)

HA-LAN using LinuxHA and DRBD

[edit]


If you have some notes, please contact T.J. Yang <tj_yang (at) hotmail.com>
to submit it to the wiki

Hi,

for the failover part, what about using a real cluster like Linux HA cluster
with DRBD? I've setup such a system a few weeks ago for us.

 Take a look at the Xymon alert man page:

 http://www.hswn.dk/hobbit/help/manpages/man5/hobbit-alerts.cfg.5.html

 You can specify a script to be executed for any given alert.  The ALERT
 SCRIPTS section in the man page gives details of the environment variables
 passed in with the the alert information.  So, you could write a script to
 send snmp traps.

 I don't know about alert failover.

  After a bit of a hiatus from bb/hobbit/xymon issues, I'm looking at it
  again.

  I've grabbed a copy of xymon-4.4.0 svn and set it up on a test server
  here -  very nice.

  As hope springs eternal, I'm again hoping to replace our aging big
  brother servers with xymon, since it's the closest thing to a drop-in
  replacement. Hopefully xymon can be made to do some specific things that
  bb does, which we depend on here, namely:

  1. snmp traps - this is just a basic requirement to send out an snmp trap
  on an alert. We have no need to receive snmp traps, only to send them, as
  big brother does. We depend on that behavior to generate tickets by
  sending traps to netcool whenever there is a bb alert condition.

  2. alerting failover - we have redundant bb servers are set up, in pairs.
  each pair of bb servers monitors certain network segments, while only one
  of the pair is designated as the bbpager, i.e. only one of the pair sends
  out alerts. But, should the passive bbpager be unable to reach the
  normally active bbpager, failover kicks in, and the normally passive
  server begins sending out all alerts. Worst case, we have a split brain
  condition and get 2 copies of an alert, but in practice, that's only
  happened a handful of times since 2005.

  Can xymon 4.4.0 do these things, or is there a way to implement this
  behavior with some appropriate add-ons?

  Joe
