ahhdem I see your point about stacking graphs but I just get around that by using line graphs instead of areas. Solves the problem of overlapping just fine. Unfortunately, I discovered a new problem and that's a real downer. Turns out some graphs only retain data for 3 days instead of 7. The 2 affec...

BTW the error when adding a host is this This data query returned 0 rows, perhaps there was a problem executing this data query. You can run this data query in debug mode to get more information. The debug looks fine + Running data query [10]. + Found type = '4 '[script query]. + Found data query XM...

I also noticed that the cpu graph scales to 120% eventhough the percent idle never exceeds 100. Is that desired ? I also saw that the graph uses the STACK Item Type for most stuff. Doesn't this mean that graphs are stacked on top of each other thereby giving totally wrong values ? Inever understood ...

EXCELLENT WORK ! This is the first time someone posted something really useful and complete regarding linux perfstats not relying on awful snmp. Still not quite a full sar report but THIS much closer ! I absolutely agree that the out-of-the box stuff is pretty useless except the FS and NIC stats whi...

I guess I answer my own post.
I tried it again step-by-step and this time it worked. I think I deleted something I shouldn't have.
Anyway now I have the nice tcp stats back but without killing cacti when the hosts are under load.
ssh rulez !

Gurus I used the snmpnetstat based perl script from Gandalf to graph tcp connections and it was fine until I noticed that it will seriously hang on a very busy webserver. So bad that it kills all graphs for this host. Even when you crank up all timeouts very high. I tried running 'netstat -at' over ...

Guys I used this script for a while until we had an issue where our webservers got into the range of 8000 connections. Now I cannot use snmpnetstat at all on these. It simply doesn't return anything - it just hangs indefinitely. No wonder cacti can't graph it. Funny thing the load on those webserver...

To answer my own post. I seem to have stumbled upon a solution by accident. Click on "Data Sources" Pick the host in question Click on the name of the partition in question Under "Custom Data" change "Index Type" from "dskIndex" to "dskPath" I tried ...

If I could just index by volume name that would work since those are already persistent. Not sure why I'd need labels as well. The problem remains how do I tell cacti to use volname/label instead ?

Witness Are you saying the problem is with net-snmp and everyone using cacti with net-snmp will have that problem ? Or is the problem with the way cacti uses data queries for net-snmp by default ? I'm not very savvy with snmp at all - I just use the wizard to add more devices. How is everybody deali...

Guys I can't believe I haven't found anything about that on here and maybe I didn't search long enough but I'm pulling my hair out here. It seems that certain oids don't persist accross reboots. F.e. I monitor all my RHEL4-U7 boxes via snmpv2 and I noticed the following. Disk usage for local drives ...

Guys Any news on the 16-way template ? Also I have found that the new templates don't graph quite the way the old ones did. It used to adjust the max based on the average of the utilisation. Since I applied the new graps it always shows the 100% mark even if utilization is very low. Doesn't make for...

nah never mind. I tried it and it's a pain. Some of those don't import at all and the others require too much manually mangling.
Besides they look messy on 16 way box anyway.
I'd rather wait on your 16 way template.

thanks

Guys what do you think about this thread ?

Sure tempting to get each cpu graphed separately as well...

Well if you really go by what linux sees as a cpu then it's 16. I already knew that cause when you do a 'top' and press '1' it shows 16 cpu's there ( your test confirms too) but I thought you were referring to cores only and this box has 8. I always thought a core is real whereas HT is not considere...
