poller.php don't polling my snmp device

Post by arjanv »

My poller.php don't want to poll my snmp device.
My snmp devices gives status unknown, but I get under devices the following information at the top of the page :
SNMP Information
System: Linux localhost 2.6.9-1.6_FC2 #1 Thu Nov 18 22:03:19 EST 2004 i686
Uptime: 697892
Hostname: localhost

I have made a traffic graph, but is a very empty graph.

Who must I do so my poller.php is going to poll my snmp device?

snmp

Try to get the data via cli.
Use

Code: Select all

snmpwalk -c <community> -v<snmp version> <host> system
to ask for the data you see in the heading of the host entry in cacti. e.g.

Code: Select all

snmpwalk -c public -v1 localhost system
for your local host.
This should work.
Now try to get other information, e.g. about the interfaces. Use

Code: Select all

snmpwalk -c public -v1 localhost interface
or substitute localhost by the hostname/IP@ you are worried about. I suppose this will not work in your case. Perhaps you have to configure the snmpd of the host in question. Look for /etc/snmpd.conf.
Also look at the device under MAnagement -> Device -> <your device> and see the section Associated Data Queries If the status does not show any success, the snmp request fails. Online debugging is possible via (Verbose Query).

Maybe some explenation. I have some graphs for the locahost(127.0.0.1) in Cacti is this a local Linux Machine. Now I wan't to monitor the bandwith of the local networkcard eth0. I have made the local networkcard as a snmp interface.
Also look at the device under MAnagement -> Device -> <your device> and see the section Associated Data Queries If the status does not show any success, the snmp request fails. Online debugging is possible via (Verbose Query).
+ Running data query [1].
+ Found type = '3' [snmp query].

Is this enough information, i don't know how to fix my problem?
Hope anyone can help me?

SNMP agent

Post by zanaguara »

Your SNMP agent is responding with no interface information.

Try running snmpconf to configure your agent.

snmpd.conf

Post by gandalf »

My local snmpd (Red Hat) has config options such as

Code: Select all

rocommunity <read only community "password"> <ip of system, that is allowed to send snmp get requests>
for example:

Code: Select all

rocommunity strangepw 192.168.1.54
You may even specify subnets, that are allowed to query. For more information, see

Code: Select all

man snmpd.conf
