Missing data (system load, memory) on OS X install

[rev_maynard3]

Hi All,

I'm running:
OS X Server 10.4.6
Apache 1.3
MySQL 4.1.13a
PHP 4.4.1
RRDTool 1.2.12


I've got Cacti up and running and as of last night it is generating SOME graphs. I get logged on users and # of processes, but so far no system load or memory usage. RRDTool is creating the images, but they're "empty".

I did a little investigation and when I run the "poller" command at the CLI I get the following:

Code: Select all

# php /Library/WebServer/Documents/cacti/poller.php
cat: /proc/meminfo: No such file or directory
cat: /proc/meminfo: No such file or directory
OK u:0.01 s:0.02 r:0.02
OK u:0.01 s:0.02 r:0.02
ERROR: Not enough arguments
OK u:0.01 s:0.02 r:0.02

Indeed /proc/meminfo doesn't exist... I think that's a Linux thing? and I'm not sure what the "ERROR: Not enough arguments" is referring to... Can anyone help?


Thanks!

I should have also included the following:

Code: Select all

# php /Library/WebServer/Documents/cacti/cmd.php
cat: /proc/meminfo: No such file or directory
05/01/2006 10:15:32 AM - CMDPHP: Poller[0] Host[1] DS[3] WARNING: Result from CMD not valid.  Partial Result: 
cat: /proc/meminfo: No such file or directory

05/01/2006 10:15:33 AM - CMDPHP: Poller[0] Time: 0.3630 s, Theads: N/A, Hosts: 1

Similar to the poller.php output, but gives a little more information...

These templates rely on /proc/meminfo (memory usage). System load depends on support for UCDAVIS MIB OIDs. Please try a

Code: Select all

snmpwalk -c <community> -v 1 <target> ucdavis

If this works, cacti should get data.

Although I believe that I've configured SNMP correctly, and likewise I confirmed that snmpd is running and listening (on UDP port 161), I received the following when I ran your suggested query:

Code: Select all

# snmpwalk -c snmp_readwrite -v 1 127.0.0.1 ucdavis
Timeout: No Response from 127.0.0.1

I also tried this with "-v 2c" just to test... same result.


Any additional help would be greatly appreciated.

As a linux user, I don't know that much about OS X and its SNMP implementation. Perhaps there's a net-snmp port? Then, please try
