My graph do show any more data

[zinda....@googlemail.com]

Hello,

I'm using vmktree 0.3.0 with 2 esx 3.5. I maked a test last week and
vmktree worked good. But today, i checked vmktree but nothing,actually
no, there are always my 2 esx with them vm's and the differents board
(cpu0,memory,disk...) but graph does not show any data .I don't know
why.

I'm using a debian. And I run the vmktree in web
browser.
inside /var/lib/vmktree contains the subdir are sys,vm,net and my esx
and vm's.

I need the help.

PS:sorry for my english, i'm french:)

Hi!
1. Are you able to login (using ssh) to your ESX server's Service Console from the
machine you installed vmktree on (with the user you specified when you
added the esx host)? ssh user@esx-server
2. If data collection fails the data collector will create a file
/var/lib/vmktree/sys/<your-esxservername>.txt
What is the content in the first few lines of this file?

Hi,

1.Yes,i'm able to login (permitrootlogin=yes).It's ok for that.
2.what I did not understand is that vmktree recovers well data of my
esx and its vm but there is no data in my graphs.
The file /vm contains the vm of my esx (vm-esx1)
/sys file contains "memory.rrd, cpu0.rrd ...).

when I run the vmktree in web browser,i see my esx with vm's and the
differents graphs but no data...
it worked one time and then nothing.

Contact if you need more information.

Thank you for your response!!

zinda.

zinda,
1. Have you added any VMs with "strange" characters in the name?

2. Do you get any error messages if you run the collector manually? You can
get the syntax with the command: cat /etc/cron.d/vmktree

The command will be something like:
/usr/bin/vmktree-esx3-collector esxname username

3. What distro are you using?

The collector is invoked from /etc/cron.d/vmktree. You can comment out
a line there, wait a minute and try to run the collector manually again.

You can also use rrdtool fetch to check this. Gives more readable output
about the latest values. :)

You have graphs working for your virtual machines, but not your ESX
hosts?

You might be right about that. Data is however stored at different
locations on different distros so it could possibly help in giving you
advices based on your distro.

Hi Lars,

I become crazy:)

I acquire in the directory / sys: /esx with cpu0.rrd,
Hostmemory.rrd... esx.txt with the hardware information (pci device)
and root.txt

rrdtool fetch cpu0.rrd (for exemple) AVERAGE :
...1215006240:nan nan nan
1215006300: nan nan nan
...

date is stored :/var/lib/vmktree/sys
/net
/vm
my distrib is linux 2.6.18-5-486 i686 GNU Linux.

I despair:)

Did you try running the collector manually again after disabling the
collector in cron? Any error messages?

Looks like there are no updates.

Almost sounds like youre using Debian 4.0 :)
