[TUTORIAL] Aggregate Tracking Center logs of multiple nodes into one

[bco_]

Hello community

Multiple solutions have been already shared here to aggregate tracking center of all nodes.

Today, i'd like to share with you a new way to do it using pussh from bearstech.

TL;DR :

apt-get -o DPkg::options::=--force-confmiss --reinstall install pmg-log-tracker -y

cp /usr/bin/pmg-log-tracker /usr/bin/pmg-log-tracker.node

apt-get install git -y

rm -fr /opt/pussh

git clone https://github.com/bearstech/pussh.git /opt/pussh

cat <<'EOF' >/opt/pussh/cluster-pmg
127.0.0.1
125.545.544
EOF

cat <<'EOF' >/usr/bin/pmg-log-tracker
/opt/pussh/pussh -f /opt/pussh/cluster-pmg /usr/bin/pmg-log-tracker.node $@ 2>/dev/null | sed 's/127.0.0.1: //g;s/125.545.544: //g'
EOF

Detailed steps :
Always install latest pmg-log-tracker binary :

apt-get -o DPkg::options::=--force-confmiss --reinstall install pmg-log-tracker -y

Rename binary to .node :

cp /usr/bin/pmg-log-tracker /usr/bin/pmg-log-tracker.node

Install Git

apt-get install git -y

Clear /opt/pussh locations ( Optionnal ) :

rm -fr /opt/pussh

Clone pussh repo :

git clone https://github.com/bearstech/pussh.git /opt/pussh

Add your pmg cluster nodes into a file, where 125.545.544 is the IP of nodes. One node per line.

cat <<'EOF' >/opt/pussh/cluster-pmg
127.0.0.1
125.545.544
EOF

Create a new pmg-log-tracker file, which calls pmg-log-tracker.node of all nodes mentionned into pmg cluster nodes file, remove stderr and use sed to clear IP from response

cat <<'EOF' >/usr/bin/pmg-log-tracker
/opt/pussh/pussh -f /opt/pussh/cluster-pmg /usr/bin/pmg-log-tracker.node $@ 2>/dev/null | sed 's/127.0.0.1: //g;s/125.545.544: //g'
EOF

Results :

 

[LeFred]

is 125.545.544 representing IP address of pmg02 ?

 

[bco_]

Yep

Great tutorial, thank you for that, will the "update" of the system break this customization ?
