[csw-users] Migrating monitoring services from Linux - Munin server missing some files??

[Juergen Arndt]

Hi Kaya,

I digged a little bit deeper into the issues - so:

> drwxr-xr-x 2 munin munin  4096 Sep 14 04:40 cgi
> -rw-r--r-- 1 munin munin  2555 Sep 14 04:45 definitions.html
> -rw-r--r-- 1 munin munin  5345 Jan 24 19:40 index.html
> -rw-r--r-- 1 munin munin   473 Sep 14 04:45 logo.png
> drwxr-xr-x 2 munin munin 57344 Sep 14 21:35 optiplex-networks.com
> -rw-r--r-- 1 munin munin  3538 Sep 14 04:45 style.css

(1) optiplex-networks.com is the host, that is monitored by the munin  
installation on your linux box

(2) definitions.html, logo.png and style.css are not located in some  
obscure location but in /etc/opt/csw/munin/templates on the master  
side :-)
This is not an unsual place, you can easily find many RPMs for Linux,  
which have these files in the "templates" directory.

(3) index.html is created after /opt/csw/bin/munin-cron ran for the  
first time (and there was at least one host to check)

The last sentence is quite important :) Indeed this script doesn't run  
very well on Solaris. But you are right, I will check the permissions  
and the ownerships. But anyway, Munin runs with current settings well  
on Solaris, so this is a minor issue for some fine tuning and nothing  
critical.

You are using Linux style for your crontabs which won't work on Solaris.

Please create a cronjob for the user "munin" with the command "crontab  
-e munin". I don't know exactly what you mean with "... created a cron  
job which I inserted into /etc/cron.d" but it sounds wrong to me.

You should also use the following line for the cronjob itself:

0,5,10,15,20,25,30,35,40,45,50,55 * * * * /bin/test -x /opt/csw/bin/ 
munin-cron && /opt/csw/bin/munin-cron


I'm working on packages for Munin 1.4.3 and except the permissions  
everything seems to run fine, so I think, in the next days I will push  
out a testing version.

Let me know, if you have further problems!
