Hi net-snmp community,
I'm trying to use 'extend' functionality in 5.4.2.1 to feed indexed
graph data to Cacti. I moved away from 5.1.2 because of the script
looping issue with exec. Anyway, with 'extend', here's what I have going
on:
OS: RHEL4.6
Kernel: 2.6.9-67.0.15.ELsmp #1 SMP Tue Apr 22 13:50:33 EDT 2008 i686
i686 i386 GNU/Linux
In my smmpd.conf:
extend vhnames /usr/bin/perl /usr/local/mlms/mrtg2cacti/print_vh.pl -vhi
The perl script I'm using calls a bash program for each index instance
using perl backticks like this:
$execute_hoststats=`$hoststats getbandwidth $_
Then it prints the results and a newline.
Results of the script directly thru SSH (for verification):
./print_vh.pl -aut

Looks good, but if it goes through the snmpd agent there are issues...
Results of script through SNMP:
snmpwalk -t 120 -v1 -c public 10.201.0.116
'NET-SNMP-EXTEND-MIB::nsExtendOutputFull."vhutil"'
[nag...@nagios01 ~]$ snmpwalk -t 120 -v1 -c MMLSNMP 10.201.0.116
'NET-SNMP-EXTEND-MIB::nsExtendOutputFull."vhutil"'
NET-SNMP-EXTEND-MIB::nsExtendOutputFull."vhutil" = STRING: cat: write
error: Broken pipe
cat: write error: Broken pipe
cat: write error: Broken pipe
cat: write error: Broken pipe
cat: write error: Broken pipe

If I limit the lines of output, the breaking point seems to be at 9
lines:
The script only loops 9 times then exits with no errors:
snmpwalk -t 120 -v1 -c MMLSNMP 10.201.0.116
'NET-SNMP-EXTEND-MIB::nsExtendOutputFull."vhutil"'
NET-SNMP-EXTEND-MIB::nsExtendOutputFull."vhutil" = STRING: 0

Is this a bug, a result of my build options, and has it been addressed
yet? Thanks so much for the help.
