How to use distributed collectors ...

小猪兵兵

It is possible quite easily to install distributed collectors with
zenoss core. This document is mostly based on the following forum
thread:
http://forums.zenoss.com/viewtopic.php?t=7907
This example will use the main server as zenoss.paris.fr and a distributed collector as zenoss.noida.in.

On the main server zenoss.paris.fr, activate zenrender
1.1 Edit file /usr/local/zenoss/zenoss/bin/zenoss
if [ ! -f $ZENHOME/etc/DAEMONS_TXT_ONLY ]
?
; thenC="$C zeoctl"
C="$C zopectl"
C="$C zenhub"
C="$C zenping"
C="$C zensyslog"
C="$C zenstatus"
C="$C zenactions"
C="$C zentrap"
C="$C zenmodeler"
C="$C zenrender"
C="$C zenperfsnmp"
C="$C zencommand"
C="$C zenprocess"
#C="$C zenmail"
1.2 Launche "zenrender start"

Install zenoss core on the remote server zenoss.noid.in, but do not launch it.
2.1 Get ride of mysql, because we're going to use the central server mysql
If you are using the stack edition, modify /usr/local/zenoss/ctlscript.sh
elif [ "x$1" = "xstart" ]
?
; then
if [ "x$2" = "xmysql" ]
?
; thenif test -x $MYSQL_SCRIPT; then
###            $MYSQL_SCRIPT start
MYSQL_ERROR=$?
fi
elif [ "x$1" = "xstop" ]
?
; then
if [ "x$2" = "xmysql" ]
?
; thenif test -x $MYSQL_SCRIPT; then
###            $MYSQL_SCRIPT stopMYSQL_ERROR=$?
sleep 2
2.2 Change zenoss start to remove zenhub and add zenrender : /usr/local/zenoss/zenoss/bin/zenoss
if [ ! -f $ZENHOME/etc/DAEMONS_TXT_ONLY ]
?
; thenC="$C zeoctl"
C="$C zopectl"
###       C="$C zenhub"C="$C zenping"
C="$C zensyslog"
C="$C zenstatus"
C="$C zenactions"
C="$C zentrap"
C="$C zenmodeler"
C="$C zenrender"
C="$C zenperfsnmp"
C="$C zencommand"
C="$C zenprocess"
#C="$C zenmail"
2.3 allow the main server to snmp in file /etc/snmpd.conf
rocommunity public zenoss.paris.fr
2.4 Edit the conf files to use the main server zenhub but the local monitors
/usr/local/zenoss/zenoss/etc/zenactions.conf, zencommand.conf,
zendisc.conf, zeneventlog.conf, zenmodeler.conf, zenperfsnmp.conf,
zenping.conf, zenprocess.conf, zenrender.conf, zenstatus.conf, zensyslog.conf
zentrap.conf, zenwin.conf, zenwinmodeler.conf
monitor         zenoss.noida.in
hubhost         zenoss.paris.fr
2.5 Use the remote zope engine to use the main server engne
/usr/local/zenoss/zenoss/etc/zope.conf
mount-point /
# ZODB cache, in number of objects
cache-size 5000
server zenoss.paris.fr:8100
...
2.7 Install all needed zenpacks and plugins
This is most important if you are using nagios plugins or winexe
template. Don't forget to copy all this binaries to the remote server,
as it is this server that will run them against the devices.
2.8 fire up zenoss

On the main server zenoss.paris.fr, Add the remote zenoss as a new device
3.1 Management / Add Device : zenoss.noida.in, use the main server as collector

Configure the remote collector on the main server
4.1 Management / Collector / Add Collector : use the DNS name zenoss.noida.in as ID
4.2 Edit the newly created collector and change the "render URL" to use the zenders XML-RPC
Render URL :
http://zenoss.paris.fr:8090/zenoss.noida.in

Transfert existing devices to the remote distributor
5.1 RRD performance data are to be copied to the remote server
zenoss.paris.fr# scp -Cr /usr/local/zenoss/zenoss/perf/Devices/mydevice zenoss.noida.in:/usr/local/zenoss/zenoss/perf/Devices
5.2 don't forget to add the remote collector in devices /etc/snmpd.conf
rocommunity public zenoss.noida.in
5.3 Move the devices to the remote collector
Management / Collectors / zenoss.paris.fr
Select the devices and use "Set collector"
