Poor performance

Post by ericj77 »

I understand that this is not a "Cacti" problem, but I'm out of options and maybe somebody else out there has seen this.

The problem I am seeing is a very slow browser response while accessing cacti remotely, a good example is when I click "graph templates" or "data templates". In Opera the "template name" table just trickles onto the page and in IE it just sits there for about 30 seconds, then displays it. When accessing the page from the server itself it displays rather quickly.

I don't think it's a network problem because I can FTP back and forth at 30-40Mbps, no problem, and there's no firewall running. Both the NIC and the port are 100/full and there are no links between me and the server less than 100mbps. The Apache error log is showing no errors. I can login with the mysql client and run queries against the database and never get higher than a 0.01 response time. The server is not overburdened, it's a new install (SuSE 10.0) and is doing nothing but Cacti, and is currently only monitoring itself (localhost). I have made a few changes, altering the rra/rrd info to accomodate 1-minute polling, and I've installed the plugins patches.

The installed versions are as follows:
Cacti 0.8.6h
Apache 2.0.54
MySQL 4.1.13

Any ideas? I'm at a complete loss.

Poor performance

Post by moshesharon »

Hi

It can be happened by number of factors. please check top to see if load avg of the server is ok. check if you enabled hostnamelookups in the httpd.conf (and if your machine as dns record resolved).
other then that i suggest to make a static page and check if the poor performance to eliminate server problem and then try to narrow the problem to server itself

Hope it helps

Possibly MTU?

Post by mini4mw »

If you don't believe its a server issue and you tunnel into the network I'd check MTU on the client connecting. I've fixed a number of issue where users tunnel into a secured network and due to firewall/private IPs MSS and MTU discovery do not work correctly/able to respond.

Try hard coding the MTU to 1300 and see if there is any difference. there are a number of web sites to choosefrom if you google for instructions based on the client OS.
