ss_fping returns UNKNOWN when called from Cacti

[MrGde]

I've tried around two days with the Advanced Ping (ss_fping.php) but can't get it to work. When the script is called by Cacti it returns 100% Packetloss and U for min/max/avg - when I call it manually it works correctly:

Problem:
The logfile shows that Cacti is starting the fping correctly but then it only gets back unknown values:

Code: Select all

06/05/2012 05:15:01 PM - CMDPHP: Poller[0] Host[6] DS[71] CMD: /usr/local/bin/php /usr/local/share/cacti/scripts/ss_fping.php my.host.name 10 ICMP , output: min:U avg:U max:U dev:U loss:100.00 

When I start the the script manually as user cacti it works:

Code: Select all

# su cacti
% php /usr/local/share/cacti/scripts/ss_fping.php my.host.name 10 ICMP
min:21.1200 avg:22.5696 max:24.2470 dev:0.9942 loss:0.0000%

My setup:
- FreeBSD 9
- Cacti 0.8.8a_1
- ss_fping.php that comes with the distribution
- Cronjob running as user "cacti"

I already tried to have ss_fping called as script server - having the same issue here.

Can anyone help?

Same thing here,

I am willing to change/migrate our Ubuntu Cacti server to FreeBSD but I could not make ss_fping script work on FreeBSD.

By the way, realtime plugin graph works without any problem.

* Cacti 0.8.8a

I could not solve this problem but instead wrote a shell script which does the same thing (more or less). I know that it may be optimized way further but currently the only important thing is that it works on my FreeBSD server.

Code: Select all

#!/usr/local/bin/bash

out=`/sbin/ping -c 10 -q -t 2 $1`

loss=`echo "$out"|awk -F', ' '/loss$/ {print $3}'`
loss=${loss%\%*}

if [[ "$loss" != "100.0" ]]; then
  echo -n "$out"|awk '/^round/ {printf $4}'|awk -F'/' '{printf "min:"$1 " avg:"$2 " max:"$3 " dev:"$4}'
  echo -n " loss:$loss"
else
  echo -n "min:U avg:U max:U dev:U loss:100.0"
  fi

* I created a file named FreeBSD_Ping.sh under cacti scripts folder
* made the script file executable (chmod +x FreeBSD_Ping.sh)
* changed PING - Advanced Ping v1.3, Input Type to "Script/Command"
* finally changed PING - Advanced Ping v1.3, Input String (from Data Input Methods) as:

Code: Select all

<path_cacti>/scripts/FreeBSD_Ping.sh <hostname> <attempts> <protocol> <port>

I know this whole method is also far from acceptable (did I say I was lazy) but as I stated above it does the job...

By the way, if anyone is curious why I replaced my Cacti Ubuntu Server with FreeBSD one I would like to share some statistics:

Ubuntu Server
* 1 GB RAM
* 10 GB Disk space
* 2 CPUs
SYSTEM STATS: Time:85.2523 Method:spine Processes:2 Threads:16 Hosts:151 HostsPerProcess:76 DataSources:17831

FreeBSD Server
* 512 MB RAM
* 12 GB Disk space
* 2 CPUs
SYSTEM STATS: Time:35.5644 Method:spine Processes:2 Threads:8 Hosts:149 HostsPerProcess:75 DataSources:17053

Both servers are VMs on the same physical machine. Both Cacti have the same plugins (no Boost plugin) and polling from the same machines.

Before Ubuntu server, I had installed Cacti on a Windows server (about double the resources) and you really do not want to know the polling times.

Same thing......
FreeBSD 9.0, Cacti 0.8.8a, PHP 5.4.5
I guess it is PHP related issue ?
