Hey again,

I thought I might specify what I'm trying to achieve since I might just be trying the wrong way.

I would like to configure the most hosts possible by some sort of grouping or tags - the CLASS function in combination with analysis.cfg and hosts.cfg seemed to be the right way to do this. But since I'm running a pretty big network infrastructure with a lot of different hosts that run different software combinations, I need to be able to combine some check groups, i.e. the following in analysis.cfg:

CLASS=web PROC nginx 1 -1 PROC php*fpm 1 -1 PROC cron 1 -1 CLASS=db PROC mysqld 1 -1 CLASS=deb7 PROC ntpd 1 -1 CLASS=deb8 PROC systemd-timesyncd 1 -1

So I can just add the PROC checks I need via CLASS assignments in hosts.cfg and don't need to add custom configuration for every server to analysis.cfg:

page myservers My Servers group domain1 1.2.3.1 web.dom.tld # *CLASS:deb7,web* trace ssh 1.2.3.2 db.dom.tld # *CLASS:deb8,db* trace ssh 1.2.4.1 www.dom.tld # https://www.dom.tld 1.2.4.2 dev.dom.tld # https://user:pass at dev.dom.tld group domain2 1.2.3.10 srv.dom2.tld # *CLASS:deb8,web,db* trace ssh 1.2.4.10 www.dom2.tld # https://www.dom2.tld

And so on... I've got way more combinations, so manually creating combined classes like "deb7-web", "deb7-db", "deb7-web-db", etc. is not really an option.

I can't imagine I'm the first person trying to do this since actually it's pretty essential to have check groups for reduction of redundant config bloat.

Any help or hints would be really appreciated!

Kind regards and thanks in advance, David Winterstein

Hi everybody,

I didn't find something on this topic yet, so I thought I'd give it a quick try at the mailing list:

Since the class assignment now works like a charm with analysis.cfg and hosts.cfg (thanks a lot for that!) I wondered how I could possibly assign multiple classes to a host.

Given an analysis.cfg containing something like this:

CLASS=class1 PROC sshd 1 1 CLASS=class2 PROC ntpd 1 1

A hosts.cfg like this only uses the first class provided - "class1" in this case:

1.2.3.4 srv.dom.tld # CLASS:class1 CLASS:class2

While a hosts.cfg like this seems to combine both class names to the new, unhandled group "class1,class2":

1.2.3.4 srv.dom.tld # CLASS:class1,class2

Is there a solution for this already or is it not possible to assign multiple groups to a single host?

Thanks a lot in advance, David Winterstein
