NimbostratusEmpty TMM Memory graph in Cacti
Hi,
I'm pretty new to F5 world, but learning fast. I've installed Cacti in a RedHat Server to monitor some of our F5 boxes.
Following a tutorial found here I've got it up and running, almost all configured as I need.
However, I can't get the TMM memory graph to work, all the values appear as NaN. Some details:
Inside the server where cacti is installed, using the shell, I go to scripts folder and run the script manually...
php ss_f5-bigip-tmm-memory.php f5_ip public 2 161 10
sysStatMemoryTotal: 13136560128 sysStatMemoryUsed: 2379967036
I go to rra folder, and run this command using the graph from one of the boxes as argument:
rrdtool fetch vp-01_tmmmemtotal_22.rrd AVERAGE | tail
1246389600: nan nan
1246389900: nan nan
1246390200: nan nan
1246390500: nan nan
1246390800: nan nan
1246391100: nan nan
1246391400: nan nan
1246391700: nan nan
1246392000: nan nan
1246392300: nan nan
When running this other command...
rrdtool info vp-01_tmmmemtotal_22.rrd

Finally, here's the script:
[root@yblhpdefvm scripts] more f5-bigip-tmm-cpu.pl~
!/usr/bin/perl
Usage: f5-bigip-tmm-cpu.pl
use Net::SNMP qw(:snmp);
my $host = $ARGV[0];
my $snmp_comm = $ARGV[1];
chomp $host;
chomp $snmp_comm;
my $tmmTotalCyl = '.1.3.6.1.4.1.3375.2.1.1.2.1.41.0';
my $tmmIdleCyl = '.1.3.6.1.4.1.3375.2.1.1.2.1.42.0';
my $tmmSleepCyl = '.1.3.6.1.4.1.3375.2.1.1.2.1.43.0';
my ($session, $error) = Net::SNMP->session(
-hostname => $host,
-community => $snmp_comm,
-port => 161,
-version => 'snmpv2c',
-nonblocking => 0
);
if (!defined $session)
{
print "Received no SNMP response from $host\n";
print STDERR "Error: $error\n";
exit -1;
}
poll CPU oids
my $polled_oids = $session->get_request(
-varbindlist =>
[$tmmTotalCyl, $tmmIdleCyl, $tmmSleepCyl] );
calculate CPU Utilization
my $tmm_cpu = (( $polled_oids->{$tmmTotalCyl} -
($polled_oids->{$tmmIdleCyl} + $polled_oids->{$tmmSleepCyl}))
/ $polled_oids->{$tmmTotalCyl} * 100) ;
Round to integer
$tmm_cpu = int($tmm_cpu + .5);
print CPU Utilization to stdout for cli validation
print $tmm_cpu;
As I said, I'm fairly new, and I can't seem to find the problem.
Any help will be deeply appreciated.
Cheers,
Laura
