Problem with PHP script

[woueb]

Hello,
I'm facing a huge problem on a Cacti fresh install : all SNMP checks are working fine, but each PHP check return an error

I have these messages in Cacti log file

Code: Select all

10/20/2010 11:55:02 PM - CMDPHP: Poller[0] Host[12] DS[137] SERVER: /var/www/cacti/scripts/ss_netsnmp_memory.php 172.20.1.104:2:mysnmpcommunity:::::::161:500, [b]output: WARNING: Function does not exist[/b]

But when I execute the php from the command line I have a result :

Code: Select all

php -q /var/www/cacti/scripts/ss_netsnmp_memory.php 172.20.1.104:2:mysnmpcommunity:::::::161:500

Cacti is Version 0.8.7g

Please show us the parameters used when defining this Data Input Method. Did you define a plain script or a script server script?
R.

R.

Hello,
it's a Script - Script Server PHP

And the parameters are :

Code: Select all

<path_cacti>/scripts/ss_netsnmp_memory.php <hostname>:<snmp_ver>:<snmp_community>:<snmp3_username>:<snmp3_password>:<snmp3_authprot>:<snmp3_privpass>:<snmp3_privprot>:<snmp3_context>:<snmp_port>:<snmp_timeout>

Fine, but I meant to show us a screenshot of the Data Input Method as available under the related menu entry
R.

Ok, please find the screenshot attached.

Thank you,

Please replace ":" by " " for the command definition. When calling the DIM, cacti will append all named parameters, seperated by blanks (not colons).

[woueb]

Hello Gandalf,
thank you for the reply : with the same command, but the ":" replaced by " ", I still have the problem.
I don't think I sould remove theses ":".

In the PHP script, I have a line in the beginning.

Code: Select all

$protocol_array = explode(":", $protocol_bundle);

And, if I test with the ":" in the command line, it's working :

Code: Select all

Hello,
I've made additionnal testing.

I've created/reinstalled a new Cacti from scratch.
The problem seems that I'm not able to create RRD file for my PHP script.

Example :

Code: Select all

/usr/bin/rrdtool create /var/www/cacti/rra/fradephp01_apache_cpuload_146.rrd --step 300  DS:apache_cpuload:GAUGE:600:0:100 RRA::0.5:1:600 RRA:AVERAGE:0.5:1:500 RRA:AVERAGE:0.5:6:700 RRA:AVERAGE:0.5:24:775 RRA:AVERAGE:0.5:288:797
ERROR: Unrecognized consolidation function

[gandalf]

RRA::0.5:1:600

misses the consolidation function
