Extended system stats graphing- vmstat, iostat, mpstat (sar)

[elpiako]

actually I graph no windows with sarparse, only some linux hosts

[it]

i appreciate thx

[Priceadmin]

hi everybody,

in my Sarparse CPU Usage graph, i have only NAN instead of data.

i 've done all as described in this post but no data.

i'm on RH5 server, cacti 0.8.7a et NRPE 2.12.

thanks

[Priceadmin]

noboby have an idea ?

[elpiako]

does the command "check_nrpe -H <target host> -c sar" work from your cacti server ?

does any other sarparse graph work ?

[ahhdem]

hi everyone.. never expected this many users. so ashamed of my perl code now.

thanks, elpiako for being so helpful... for those of you having problems with one line of output like :
Average: procs

and thats it... be sure to grab the latest nrpe and compile it from source.. it's only requirements are typically openssl and of course gcc.. if you're on redhat just gcc and openssl-devel packages will satisfy all other requirements for building nrpe.

in my environments we've used 2.8.1 and had no problems. From the NRPE Changelog:

2.1 - 01/19/2004
----------------
- Any output from plugins after first line is now ignored before
plugin process is closed

2.8 - 05/08/2007
---------------
- Added support for multiline plugin output (limited to 1KB at the moment) (Matthias Flacke)

2.12 - 03/10/2008
-----------------
- Fix for unterminated multiline plugin (garbage) output (Krzysztof Oledzki)

so, stay current!

Would it be possible to re-work this script at all to not use NRPE and instead just use an ssh trust to the target host?

[Rael]

Also, none of the SARParse IO stuff works?

[mdxp]

The original location of this script (http://frylab.com/~adamb/sarparse/) seems to be down. Can anyone else that used them, upload them somewhere to be available for others to download? Thanks in advance!

[fazil]

hi all,
where can i download the templates and scripts of the ahhdem topic please ?

[neocontrol]

I too am looking for this tool as well. If anyone has it, can they email it to me and I'll host it up myself for others.

Please email me at:

charlie <dot> reddington <at> gmail <dot> com

[joe_hznm]

look into the word document in previous post, the tar ball included in it.

[fazil]

thank you very much. I did not pay attention we can get it here.

thx

[neocontrol]

Thanks, same here, the file just acts a bit wonky using mac ms office.

I am having 2 graphing issues, otherwise this works perfect.

The graph 'Load Average' is giving me the following from it's debug code. This graph, has yet to produce even an empty graph. It's pretty obvious that this graph has not even been created, like all the others and I have tried blowing it away, and recreating it, with no luck.

RRDTool Says:
ERROR: opening '/var/www/cacti/rra/server_007_load_1min_543.rrd': No such file or directory

And then for the memory usage graph, which also has yet to create a empty graph as well, is giving a differnt error, that I'm not sure what it means. The RRD file does exist, but it's not getting updated, as the file size is staying the same.

ERROR: the RRD does not contain an RRA matching the chosen CF

I'm not getting any errors or warnings for these 2 graphs.

I am using a modified sarparse.pl script that pretty much strips out the nrpe stuff since I will eventually use this remotely with out that.

My output from sarparse is...
