Hi,

I’m trying to create some performance graphs but when i look in the debug.log file from nagiostat I get the folowing.

**INCOMING PERFDATA:
LASTCHECK=$
HOSTNAME=FSLYL
SERVICEDESCR=“PING"
SERVICESTATE=“OK"
OUTPUT=”$“
PERFDATA=”$”
**WARNING: Hostname and description didn’t match any of the regexes in the config-file.

My misccommands.cfg contains:
define command{
command_name process-service-perfdata
command_line /usr/local/nagios/nagiostat -p "$LASTCHECK$|!!|$HOSTNAME$|!!|$SERVICEDESC$|!!|$SERVICESTATE$|!!|$OUTPUT$|!!|$PERFDATA$
}

Any id why the other variables aren’t filled in the debug.log file ?

Nagios is v2.0rc2

you are using nagios1.x macros

use SERVICEOUTPUT, LASTSERVICECHECK and SERVICEPERFDATA.

Thanks luca,

The correct data is now filled in and a file is created in nagiostat/archives.
But whenever I go from nagios and try to see the graph I get:
"You don’t have permission to access /nagiostat/nagiostat.cgi on this server. "
Looking in the apache log I get:
“Symbolic link not allowed”

Nagios runs under user nagios and is member of nagcmd.
Apache runs under user wwwrun and is member of nagcmd.

-rwxrwxr-x 1 nagios nagcmd 19705 Jul 6 2004 nagiostat
lrwxrwxrwx 1 nagios nagcmd 9 Jan 18 13:05 nagiostat.cgi -> nagiostat

Whenever I do su nagios or su wwwrun in a shell, I can run nagiostat.cgi

Can you also tell me where I can find some info and examples about nagiostat.conf.

Regards,

Rene

What are the permissions on the nagiostat directory?

the nagiostat.conf file is quite self explanatory. most diffiuclt part for me were the regexes which i had never done at that time… :smiley: for the ping/RTA values you just ned to chenga ethe hostnames in the example file and you should get something usable.

Luca,

The rights for the directory is as follow:

drwxr-xr-x 9 nagios nagcmd 224 Jan 18 13:07 .
drwxr-xr-x 14 root root 360 Jan 17 12:06 …
drwxrwxr-x 2 nagios nagcmd 104 Jan 18 11:24 bin
drwxrwxr-x 3 nagios nagcmd 368 Jan 13 16:28 etc
drwxr-xr-x 2 nagios nagcmd 1648 Jan 13 13:28 libexec
drwxr-xr-x 5 nagios nagcmd 400 Jan 19 09:04 nagiostat
drwxrwxr-x 2 nagios nagcmd 552 Jan 18 11:24 sbin

do you have the Options line in the apache conf file for your nagios host? looks like apache is blocking the FollowSymLinks option…

it should read

Options +ExecCGI

Luca,

Hereby my apache conf files.
Within nagios all cgi scripts are working.

cat nagios.conf
ScriptAlias /nagios/cgi-bin /usr/local/nagios/sbin
<Directory “/usr/local/nagios/sbin”>
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user

Alias /nagios /usr/local/nagios/share
<Directory “/usr/local/nagios/share”>
Options None
AllowOverride None
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user

cat nagiostat.conf
Alias /nagiostat/ /usr/local/nagios/nagiostat/
<Directory “/usr/local/nagios/nagiostat”>
Options +ExecCGI
Order allow,deny
Allow from all

Alias /nagiostat /usr/local/nagiostat/
<Directory /usr/local/nagiostat>
Options +ExecCGI
AddHandler cgi-script .cgi
Order allow,deny
Allow from all

this is what i have…
the line “AddHandler cgi-script .cgi” is missing in your config but i don’t think it’s this…

not sure what else could be wrong…

Added the line:
"AddHandler cgi-script .cgi"
But the result is the same.
"You don’t have permission to access /nagiostat/nagiostat.cgi on this server. "
Looking in the apache log I get:
“Symbolic link not allowed”

Rene

try adding explicitly the symbolic links option…

Options +ExecCGI +FollowSymLinks
not sure if the + has to be on every parameter or not…

Luca,

That seems to do it.
message now is Graph doesnot exists.

I call nagiostat as follow:
/nagiostat/nagiostat.cgi?graph_name=fs_lyl-ping

good. :slight_smile: Now you have to edit nagiostat.conf.
read the comments and you should find all you need to get at least a ping graph running :slight_smile:
