openvz container load monitoring

[uid0]

Hello everybody!

I need your help. I am trying since 2 days to monitor all openvz containers by load but i dont have any success.

I want, that zabbix agent runs "vzlist -o veid,laverage -H" and the zabbix server imports the veid and laverage. Then i want to create a trigger of load 1min/5min/15min.

Output of vzlist -o veid,laverage -H would be:

100 0.00/0.00/0.00
130 0.00/0.00/0.00
140 0.40/0.22/0.19
150 0.00/0.00/0.00
160 0.00/0.00/0.00

Could somebody *please* give me tips how i could do it and how zabbix can split the result of vzlist to make a trigger? I play since 2 days and have no success. I am not such a expert but have read already serveral faqs without goals

Would be really, really awesome if somebody could help me out.

Thanks a lot!

You need to split/parse the values before sending them into Zabbix.

You could use something like that:

#!/usr/bin/perl
use strict;

open(IN, "vzlist -o veid,laverage -H |") or "can't spawn: $!";
while (my $l = <IN>)
{
if ($l =~ /^(\d+) (.*?)\/(.*?)\/(.*?)$/)
{
my $id = $1;
my $v1 = $2;
my $v2 = $3;
my $v3 = $4;
print "zabbix_sender -z <your_zabbix_server> -s <your_zabbix_host> -k laverage_on_$id\[v1] -v $v1\n";
print "zabbix_sender -z <your_zabbix_server> -s <your_zabbix_host> -k laverage_on_$id\[v2] -v $v2\n";
print "zabbix_sender -z <your_zabbix_server> -s <your_zabbix_host> -k laverage_on_$id\[v3] -v $v3\n";
}
}
close(IN);

Substitute the "print" sequences with correct values.

Hello,

thanks for your help. I tryed it but zabbix dont display the values. There is nothing about it in the zabbix logs.

I changed the script to this:

#!/usr/bin/perl
use strict;

open(IN, "vzlist -o veid,laverage -H") or "can't spawn: $!";
while (my $l = <IN>)
{
if ($l =~ /^(\d+) (.*?)\/(.*?)\/(.*?)$/)
{
my $id = $1;
my $v1 = $2;
my $v2 = $3;
my $v3 = $4;
print "zabbix_sender -z 10.0.0.4 -s 10.0.0.1 -k laverage -v -o $id\n";
print "zabbix_sender -z 10.0.0.4 -s 10.0.0.1 -k laverage -v -o $v1\n";
print "zabbix_sender -z 10.0.0.4 -s 10.0.0.1 -k laverage -v -o $v2\n";
print "zabbix_sender -z 10.0.0.4 -s 10.0.0.1 -k laverage -v -o $v3\n";
}
}
close(IN);

My itemconfiguration is this:

If i manually send a string over zabbix_sender then it get added into zabbix. Maybe there is something missing in the script?
It seems that there get nothing sended, because "Last check" dont change in zabbix. There is still the date of my manual string.

My skills at perl and bash are very limited, i hope there is some help for me.

Thanks a lot!

First:
the "print" statements only _PRINTS_ the commands. Copy and paste them into your shell to see if the values make it to zabbix. Then change "print" to "system", e.g.:

system ("zabbix_sender -z <your_zabbix_server> -s <your_zabbix_host> -k laverage_on_$id\[v1] -o $v1");

and repeat that for all needed values to send.

Second:
With your changes, you're overwriting the values for the key "laverage". Thus I scripted to use different keys (-k laverage_on_$id\[v1] ...)

What is the script output if you launch it in a command line?

P.S. Sorry, I had an error, "-v" must be "-o". Mea culpa. "-v" is "verbose". You may omit that.

This is under the assumption, that your posted lines

100 0.00/0.00/0.00
130 0.00/0.00/0.00
140 0.40/0.22/0.19
150 0.00/0.00/0.00
160 0.00/0.00/0.00

do mean:
ID value1/value2/value3

You cannot put all three values to the same key "ID".

Therefore I created 3 keys:

laverage_on_{ID}[v1]
laverage_on_{ID}[v2]
laverage_on_{ID}[v3]

which you can use to store all three values:

laverage_on_{ID}[v1] = value1
laverage_on_{ID}[v2] = value2
laverage_on_{ID}[v3] = value3
