[gandalf]

Thanks for posting that. I will give it a try. Does anyone know, what additional OIDs whould yield interesting results?

If we could get these graphs to work, I'd like to see these:

Code: Select all

SQUID-MIB::cacheRequestHitRatio.1 = INTEGER: 0
SQUID-MIB::cacheRequestHitRatio.5 = INTEGER: 0
SQUID-MIB::cacheRequestHitRatio.60 = INTEGER: 0

Hey guys, i have some other templates that i use to monitor my squid servers and their performance. Hopefully they help someone else.

Would you please mind to post some screenshots?

Hey,

I'm trying to import these templates, but recieve following error:

Code: Select all

Error: XML: Hash version does not exist.

I'm doing in the left menu 'import templates'
I'm using cacti 0.8.6h

I experience the same. It's because the graphs were exported with version 0.8.6j.

bshoebottom - is there any way you can backport these to version 'h' or 'i'? I'd really like to use the templates you've offered but the debian cacti release that I use is frozen at 0.8.6i.

[bshoebottom]

are there working backport instructions available? I can try, but have a limited schedule.

To be honest, I don't think so. I guess I'll have to wait for Debian/testing to upgrade to 0.8.6j.

Hi All,

I get the following error with the HTTP DATA template from rrdtool and I'm a bit stumped. I tried to hunt through and find what could be causing the problem but I am a bit lacking in knowledge with rrdtool.

Any suggestions out there?

Thanks,
David

Ok, the problem is with this line;

Code: Select all

CDEF:cdefi=cdefa,0,EQ,0,cdefb,100,*,cdefa,/,1024,/,IF,0,110,LIMIT,TIME,1175219125,GT,a,a,UN,0,a,IF,IF,TIME,1175219125,GT,b,b,UN,0,b,IF,IF,TIME,1175219125,GT,c,c,UN,0,c,IF,IF,TIME,1175219125,GT,c,c,UN,0,c,IF,IF,+,+,+,*,1024,* \ 

The 'cdefb' doesn't exist and instead is called cdefe. I fixed the problem by going to Graph Management -> CDEFS and edit the Squid - Calculate Percentage of Storage item. Edit the first item and changed cdefb to cdefe.

The HTTP Data template doesn't work for me as the graph doesn't appear. When I turn on debugging for the Graph Template the drop-down box for the Graph Template list doesn't fully populate and the page doesn't finish loading. Also, in the apache logs the child process keeps crashing:

[Thu May 03 16:50:45 2007] [notice] child pid 10456 exit signal Segmentation fault (11)
[Thu May 03 16:50:47 2007] [notice] child pid 10487 exit signal Segmentation fault (11)

Gentoo Linux AMD64 2.6.18-hardened
cacti-0.8.6j-r4
net-snmp-5.4
apache-2.0.58-r2
php-5.2.1-r3

I tried apache & php with and without threads, didn't make a difference though.

[fajarpri]

Yes, same here.
HTTP-DATA doesn't show any graph.

I'm on OpenSuse10.2

All the other graphs shows wonderfully though.
Very nice

Graph Templates -> Squid - HTTP Data -> Clear Unit Grid Value textfield.
It worked on my installation (cacti 0.8.6j).
