Simple shell-script doesnt work

[porkenza]

Hello all,

i have a simple shell-script, when i run the script as user cacti direct from the command line it works, but not when the poller runs the script.

Script:
FILE="/tmp/proxy"
proxy21=$(cat ${FILE} | /usr/bin/grep "10.x.x.x" | /usr/bin/grep "Masq" | /usr/bin/awk 'BEGIN {FS=" "} {print $5}'|tr -d '\012')
proxy22=$(cat ${FILE} | /usr/bin/grep "10.x.x.x" | /usr/bin/grep "Masq" | /usr/bin/awk 'BEGIN {FS=" "} {print $5}'|tr -d '\012')
proxy23=$(cat ${FILE} | /usr/bin/grep "10.x.x.x" | /usr/bin/grep "Masq" | /usr/bin/awk 'BEGIN {FS=" "} {print $5}'|tr -d '\012')
/usr/bin/printf "proxy21:%s proxy22:%s proxy23:%s" ${proxy21} ${proxy22} ${proxy23}

Output (Commandline) as user cacti:
proxy21:207 proxy22:217 proxy23:215

Output cacti log:
output: proxy21: proxy22: proxy23:

I can't find my mistake, can someone assist?

Thanks in advance

regards,

Porkenza

Try to specify "cat" and "tr" with absolute pathname.

Same result, no data in cacti.

Then, try to investigate the results when your script was performed from cron, as like this.

ok, i had to add the following line to the script, then it works under cron:

#!/bin/bash
. /home/cacti/.profile
proxy21=$(/bin/cat /tmp/proxy | /usr/bin/grep "10.3.81.21" | /usr/bin/grep "Masq" | /usr/bin/awk 'BEGIN {FS=" "} {print $5}'|/usr/bin/tr -d '\012')
proxy22=$(/bin/cat /tmp/proxy | /usr/bin/grep "10.3.81.22" | /usr/bin/grep "Masq" | /usr/bin/awk 'BEGIN {FS=" "} {print $5}'|/usr/bin/tr -d '\012')
proxy23=$(/bin/cat /tmp/proxy | /usr/bin/grep "10.3.81.23" | /usr/bin/grep "Masq" | /usr/bin/awk 'BEGIN {FS=" "} {print $5}'|/usr/bin/tr -d '\012')
/usr/bin/printf "proxy21:%s proxy22:%s proxy23:%s" ${proxy21} ${proxy22} ${proxy23}

But the same result in the cacti log, no data.

Then, try:
1) System Utilities -> Rebuild Poller Cache
2) Delete the RRD file or/and Re-create the datasource (and graph)
