Zimbra very slow today

[rmvg]

Zimbra is very slow today and keeps giving me the server is slow to respond errors in the GUI. I know this is a very general question but what can I do to troubleshoot. I have checked the zimbra.log and everything there seems fine what are the other logs i can check? Are there some test i can run? Is there a good bandwidth monitoring tool for fedora mabey someone one the server is hogging all the bandwidth? Not sure what to do just some pointers would be appriciated

thank you

ps I shutdown the server down last night for backup could things be out of sync now??

What's the CPU, memory and disk like? Are there any processes taking up excessive resources?

[rmvg]

seems ok guessing it is bandwidth issue of some type but mabey memory is it normal for zimbra suite to eat all ram and most of swap space? I there a way to find out what users are on line and how much resource they are using? ie if one user decides to dump 3 gigs of email into zimbra is there a way for me to see what is going on?

Your cpu is idle. I notice that you've only got 512m ram? That's the low end of the supported range - if you're serious about your mail system, you should bump that up.

[rmvg]

I know i know I will up the ram but budget is limited right now. did some calling around and zimbra seems to work fine everwhere but here a my location. Phoned isp and there is no problems reported in any area today but i am guessing it is location specific. Not exactly sure what is going on thanks for the help hope it is just a bad inet day.

if you think about it, please use the "CODE" format for posting column-aligned data like that...it makes it MUCH easier to read when it shows up in a fixed-width font.

You can mark text as "CODE" by highlighting it and then clicking on the little hashmark "#" in the font bar.

Here's an example:

Normal paste from vmstat:
procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu----
r b swpd free buff cache si so bi bo in cs us sy id wa
1 0 6704 279724 12792 334584 2 1 28 27 17 21 28 1 67 4
1 0 6704 279796 12792 334584 0 0 0 0 1022 295 50 0 50 0
1 0 6704 279796 12800 334576 0 0 0 116 1026 299 50 1 50 0


Formatted as "code":

procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu----
 r  b   swpd   free   buff  cache   si   so    bi    bo   in    cs us sy id wa
 1  0   6704 279724  12792 334584    2    1    28    27   17    21 28  1 67  4
 1  0   6704 279796  12792 334584    0    0     0     0 1022   295 50  0 50  0

Which one would you rather read/debug?

[rmvg]

Thanks Tim i will post a code from now on.

Turns out that the server and zimbra are working very well. It was just my connection at work I will do some more digging tommorow to try and find out why.

Sorry to all
