PHP Poler return no vaules, command line returns values

[fireman63]

Hi,

I am having some issues with a php script I have modified to run in cacti. My goal is to use snmp on a linux box to get memory statics. I went though the forums and found some scripts and templates others have made in the past. I then modified it to work with the newer catci via documentation I found on cacti web site.

I am only have one issue. When I test the script via script_server.php it works and returns values. When cacti runs the script via the poller (cmd.php) I returns values of 0.

I'm sure I am missing something that is in the manual (and yes I thought I read it).

This what I get when I run it from the command line:

Code: Select all

[root@devserver cacti]# php ./script_server.php
PHP Script Server has Started - Parent is cmd
/var/www/cacti/scripts/ss_netsnmp_memory_usage.php ss_netsnmp_memory_usage 192.168.80.35 PASS 2 161 500

This is what I get from the cacti logs:

Code: Select all

Any ideas?

check poller cache...
try rebuilding it.

Thanks for the suggestion. I did check the poller cache it looked good. However I did rebuild it just to make sure. Next I am going to do a tcpdump just to see what is being sent and received.

Code: Select all

Script Server: /var/www/cacti/scripts/ss_netsnmp_memory_usage.php ss_netsnmp_memory_usage 192.168.80.35 PASS 2 161 500

So I did some tcpdump for the snmp traffic. I noticed a difference but don't know why.

When I run the code using script_server.php it makes multi snmp-get requests and receives multi snmp-get replies, one for each OID.

When the poller runs the code it makes one snmp-get request with multi OID request and gets a response, all 0's for values.

Is this a feature of the poller?

Sorry, missed some info in last post.

When I look at the response packet information it had 5 OID bindings as I would expect and they all have values in the packet. However the poller does not recognize them or something.
