New Relic monitoring for cfengine client performance.

• disksize/cfengine - cfengine installation disk size

• cpu/loadaverage/1m - system wide loadaverage 1 minute

• cpu/loadaverage/5m - system wide loadaverage 5 minutes

• cpu/loadaverage/15m - system wide loadaverage 15 minutes

• cpu/tasks/active - number of currently runnable kernel scheduling entities (processes, threads)

• cpu/tasks/total - number of kernel scheduling entities that currently exist on the system

• memory/rss/average/'command_name' - RSS memory usage, sampled by 1s, if NewRelic sampling inerval is larger, 1s samples are averaged. Unit: [KB]

• memory/rss/max/'command_name' - Max RSS memory usage, sampled by 1s, if NewRelic sampling inerval is larger, largest sample is reported. Unit: [KB]

Requires golang toolchain.

sudo apt-get install golang

go get github.com/yvasiyarov/newrelic_platform_go
go get github.com/maciejmrowiec/cf_client_monitor
go build

• -interval=1: Sampling interval [min]
• -key="": Newrelic license key (required)
• -verbose=false: Verbose mode

To deamonize in backgrund you can use:

nohup ./cfclientmonitor -key=<my_newrelic_key> >/dev/null 2>&1 &

Depends on:

• 'du' command
• /proc/loadavg
• 'ps -aux' with 6th column RSS and 11th column command name
