Re: Can't locate RRDs.pm or HTML/Template.pm

Hi Lupe,

Thanks for your help. Following your advice, I
installed those RPMs and now got Munin basically work.
Now the problem is I couldn't get plugin work. Could
you point out what was wrong? --  I hope this is my
last post on this thread:)
This is what I did:
1. I created file plugin.conf under
$CONFDIR/plugin-conf.d
which contains very simple config:
[cpu]
user root

2. I put the plugin script cpu (copied from Munin
installation) under $CONFDIR/plugins

3. Restart munin-node (I have two Munin instances
installed because of the RPM installation. I use the
instance installed by rpm (1.2.4) as the server and
the previously installed instance (1.3.2) as the
client/node)

4. I did NOT modify munin.conf (because it should
graph all unless we specify "[service].graph no". I
also tried adding "cpu.lable cpu" etc to munin.conf.
It didn't work.

5. Manually execute munin-cron. Then I found below in
the munin-node.log

2006/12/13-20:59:36 CONNECT TCP Peer:
"127.0.0.1:47574" Local: "127.0.0.1:4949"
Insecure directory in $ENV{PATH} while running with -T
switch at ./munin-node line 482, <STDIN> line 2.
2006/12/13-20:59:36 [30074] Plugin "cpu" exited with
status 2304. ----
Insecure directory in $ENV{PATH} while running with -T
switch at ./munin-node line 482, <STDIN> line 3.
2006/12/13-20:59:36 [30074] Plugin "cpu" exited with
status 2304. ----

6. In the browser http://localhost/munin
I didn't see any graph. i.e., if I click the localhost
link, no graph shows up.

Did I miss any plugin config?
