I’ve released a new version of my Cacti host templates for Unix systems (HP-UX, Solaris and Linux).

This new version introduces the following changes:
* ucd Load Average GT seemed somehow messed up in v1.2 (load5min missing in xml, reported by eyechart). I think it is solved now.
* New Uptime GT (all OS, contributed by Mikf here)

*WARNING*: Import each Host Template twice!!
It seems that sometimes the templates are not correctly imported after the first import (associated grath templates and/or data queries are missing). Importing the templates *once again* seems to solve the problem (at least in cacti 0.8.6g).

CactiFeel free to download version 1.3 of my Cacti host templates for Unix, and use and/or redistribute it under the terms of the GPL license.

v1.2 of my Cacti host templates for Unix

Here is a new version of my Cacti host templates for Unix systems — read HP-UX, Solaris and Linux machines and maybe other Net-SNMP compatible OS.

This new version introduces the following changes:
* I’ve splitted the “Solaris Linux ucd/net-snmp” template into two separated flavours. That way I’ll be able to tweak the graph templates of each OS according to its own particularities;
* one example of this is the CPU graph template: while in the Linux template it show nice, sys and user %CPU, in the Solaris version it now shows: kernel, wait (instead of system) and user CPU. I’ve also removed nice CPU as it won’t graph on a Solaris box.
* I’ve removed the Detailled memory graph from the Solaris template, as Solaris doesn’t seem to report such detailled metrics . It’ll only be in the Linux flavour.

Feel free to download version 1.2 of the Unix Template Set for Cacti, and use and/or redistribute it under the terms of the GPL license.

Open question: Does any of the net-snmp templates I provide (Linux or Solaris flavour) produce good results for AIX hosts? Have somebody tried it?

UNIX Template Set for Cacti

Following my first cacti host template (v1.0, see this previous post), which allows to graph some usefull performance metrics of HP-UX boxes, I was missing an equivalent (and somehow homogeneous) host template for Solaris and Linux boxes.

So I’ve reworked and adapted some existing graphs and data templates, basing me on the one available for Net-SNMP compatible hosts, and also creating new ones.

Now my Unix Template Set for Cacti is composed of 2 host templates:
* my HP-UX host template (see changes below),
* a Net-SNMP compatible host template (working well for Solaris and Linux host for example).

Both templates gives the same graphs, using the same colors… They allow graphing of the following metrics:
* CPU Usage: Sys, Nice, User and Idle CPU time
* Jobs Average: 1, 5, and 15min Jobs Average
* Memory occupation,
* Detailled Memory: part of used memory dedicated to buffers, cached and shared (available for Linux only, as neither Solaris nor HP-UX report such detailled information),
* Swap occupation
* Running Processes
* Logged in Users
* Lan traffic: In/Out Traffic and In/Out Errors
* Filesystem occupation

I’ve also apported some minor changes to version 1.0 existing graphs templates:
* CPU graphs now give a total of 100%,
* HP-UX load average is correctly rendered (value divided by 100, as the snmp agent report it multiplied by 100).

Feel free to download version 1.1 of the Unix Template Set for Cacti, and use and/or redistribute it under the terms of the GPL license.
