I am facing some problems with the monitor plugin.

When I enter on the cacti server and run the snmpwalk, it gives me all the information about the host (that is configured correctly, snmp comunity and security settings).

When I enter on the monitor page, this server appears as down (I am facing the same problem with other servers, but the status is "Unknown").

Is there something I can do to refresh the monitor plugin?

Rgds,

The poller would need to run at least once to determine the status of this host. Is the poller configured and returning data ?

You also need to graph at least one data source before Cacti will determine the device status.

Thank you for answering my question!

The poller is configured to run as the cron:

*/5 * * * * /usr/bin/php /var/www/html/cmd.php > /dev/null 2>&1
*/5 * * * * /usr/bin/php /var/www/html/poller.php > /dev/null 2>&1
00 01 * * * /var/www/backup.sh

I already monitor other servers, there are 50% green and the rest of it down or unknown.

When you say you can "walk" the servers from Cacti, are these hosts actually having any data in terms of graphs collected by Cacti ?

[caio.cesar]

No... There is this error on the device description:

SNMP Information
SNMP error

I mean when I run the linux command "snmpwalk":

/usr/bin/snmpwalk -Os -c "comunity" -v 1 "serverip"

It shows the result... But when I check on the server status on cacti, it's down/unknown...

[caio.cesar]

nothing yet... maybe there is to much data... there are 100~ servers to monitor... I have checked my database and everything is ok...

when I run the cmd.php , this ERROR appears:

09/21/2009 09:51:43 AM - CMDPHP: Poller[0] Host[152] DS[862] WARNING: Result from SNMP not valid. Partial Result: U

I found the problem.

The cmd.php was running in 5/5 minutes, I changed to 2:

*/2 * * * * /usr/bin/php /var/www/html/cmd.php
