poller.php not updating rrd files when using scripted data..

[ed201971]

Hi,

First things first:

FreeBSD 4.7
PHP 4.3.8
mysql-4.0.20
ucd-snmp-4.2.5n (ports)
rrdtool-1.0.49
cacti-0.8.6e

I have a somewhat strange issue with the poller script updating a series of rrd files. I have setup various routers and servers using the templates provided and all works swimmingly the problem comes when updating rrd files that are the target of a script.

<?php

get_bonded_sum($argv[1], $argv[2]);

function get_bonded_sum($ip, $snmpcom) {

//declare snmp mibs
$mib=".1.3.6.1.2.1.2.2.1.2";
$inoct="interfaces.ifTable.ifEntry.ifInOctets.";
$outoct="interfaces.ifTable.ifEntry.ifOutOctets.";

//walk the router...
$snmp=@snmpwalk($ip, $snmpcom, $mib);

$c=0;
$sum_in=array();
$sum_out=array();

foreach($snmp as $v) {

//split the snmp output to only return oid for each int
list ($oid, $foo)=split(" ", $v, 2);
$int=preg_split('/ifDescr+./', $oid);
$oid=$int[1];


//extract interfaces from snmp array and clean up
list ($foo, $value)=split("=", $v, 2);

if (preg_match_all('/ATM.*?\s*?subif$/', $value, $foo)) { continue; }
if (preg_match_all('/ATM.*-atm.\s*layer$/', $value, $foo)) { continue; }
if (preg_match_all('/ATM.*-aal5.\s*layer$/', $value, $foo)) { continue; }
if (preg_match_all('/ATM.*-fast/', $value, $foo)) { continue; }
if (preg_match_all('/ATM.*-int/', $value, $foo)) { continue; }
if (preg_match_all('/ATM.*-adsl/', $value, $foo)) { continue; }
if (preg_match_all('/Dialer.*/', $value, $foo)) { continue; }
if (preg_match_all('/Virtual.*/', $value, $foo)) { continue; }
if (preg_match_all('/Token.*/', $value, $foo)) { continue; }
if (preg_match_all('/Null.*/', $value, $foo)) { continue; }
if (preg_match_all('/BRI.*/', $value, $foo)) { continue; }
if (preg_match_all('/Tunnel.*/', $value, $foo)) { continue; }
if (preg_match_all('/Fast.*/', $value, $foo)) { continue; }

//get snmp data for each router
else {

$in=snmpget($ip, $snmpcom, "$inoct"."$oid");
$out=snmpget($ip, $snmpcom, "$outoct"."$oid");

//sort some data so we can choose relevant interfaces
list ($foo, $speedin)=split(":", $in, 2);
list ($foo, $speedout)=split(":", $out, 2);

}

$sum_in[$c]=$speedin;
$sum_out[$c]=$speedout;
$c++;

}

$total_in=0;
foreach($sum_in as $k=>$v) {
$total_in+=$v;
}

$total_out=0;
foreach($sum_out as $k=>$v) {
$total_out+=$v;
}

echo "bonded_in:$total_in ";
echo "bonded_out:$total_out";

}

?>


The script it self is to calculate aggregated data from CPE atm interfaces and simply returns two outputs. If I use rrdtool update to update the rrd files all works fine (this is the exact same syntax as returned by the poller) but if I leave the cron to its own devices I get no data in the rrd files!

# cacti poll
*/5 * * * * /usr/local/bin/php /home/cactiuser/cacti/poller.php > /dev/null 2>&1

I have set up all the relevant data/graph templates and data sources as required and all appears ok - there are no errors generated just no data.

/usr/local/rrdtool-1.0.49/bin/rrdtool create \
/usr/local/src/cacti-0.8.6e/rra/rmd_haydock_get_bonded_sum_70.rrd \
--step 300 \
DS:bonded_out:GAUGE:600:0:U \
DS:bonded_in:GAUGE:600:0:U \
RRA:AVERAGE:0.5:1:600 \
RRA:AVERAGE:0.5:6:700 \
RRA:AVERAGE:0.5:24:775 \
RRA:AVERAGE:0.5:288:797 \
RRA:MAX:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797 \

Here is the relevant out put from the poller:

07/01/2005 02:01:30 PM - POLLER: Poller[0] Parsed MULTI output field 'bonded_in:7540539636' [map bonded_in->bonded_in]
07/01/2005 02:01:30 PM - POLLER: Poller[0] Parsed MULTI output field 'bonded_out:3033958913' [map bonded_out->bonded_out]

07/01/2005 02:01:30 PM - POLLER: Poller[0] CACTI2RRD: /usr/local/rrdtool-1.0.49/bin/rrdtool update /usr/local/src/cacti-0.8.6e/rra/rmd_haydock_get_bonded_sum_70.rrd --template bonded_in:bonded_out 1120222884:7540539636:3033958913

The only slight difference when applying the data manually using rrdtool is that I use 'N' rather than seconds since epoch thusly:

/usr/local/rrdtool-1.0.49/bin/rrdtool update /usr/local/src/cacti-0.8.6e/rra/rmd_haydock_get_bonded_sum_70.rrd --template bonded_in:bonded_out N:7540539636:3033958913

As mentioned above using the rrdtool manually works ok? I have ensured all file permissions are ok etc and AFIACS cli php is working fine ~ can anyone offer any ideas???


TIA,

First note:

Should be "COUNTER" and not "GUAGE".

DS:bonded_out:GAUGE:600:0:U \
DS:bonded_in:GAUGE:600:0:U \

You need to push the entire "DEBUG" output for me to comment more.

Ah - silly me, I have done this I will see if this makes a difference and if not post the debug.

Thanks for the quick reply!

I have made this change but still no data - which debug do you need to see?

Data Source: rmd_wembley - Get Bonded Sum
RRD: /usr/local/src/cacti-0.8.6e/rra/rmd_wembley_get_bonded_sum_63.rrd
Action: 1, Script: php -f /home/cactiuser/cacti/scripts/get_bonded_sum.php 195.38.86.247 tr1nadsl

One thing I did notice is the following...

07/01/2005 03:25:07 PM - CMDPHP: Poller[0] Host[14] DS[70] WARNING: Result from CMD not valid. Partial Result:
07/01/2005 03:25:07 PM - CMDPHP: Poller[0] Host[14] DS[70] CMD: php -f /home/cactiuser/cacti/scripts/get_bonded_sum.php 195.38.86.242 tr1nadsl, output: U
07/01/2005 03:25:07 PM - PHPSVR: Poller[0] DEBUG: PHP Script Server Shutdown request received, exiting

What does the PHPSVR error indicate??

Here is this script being called manually - all is well?

php -f /home/cactiuser/cacti/scripts/get_bonded_sum.php 195.38.86.242 tr1nadsl
bonded_in:7555789195 bonded_out:3040482865

Thanks

Change the output line of your script to be as follows and then rerun:

Code: Select all

print "bonded_in:" . $total_in . " bonded_out:" . $total_out . "\n";

OK have done - will re run and let you know what happens

Thanks
