rtop-vis can monitor load and memory usage of all the specified servers
and visualize the data as a graph with a bit (10 minutes' worth) of history.
It connects to servers via SSH and does not need anything to be installed
on the servers. The collected data is not persisted. It is lost when rtop-vis is stopped.
rtop-vis is MIT-licensed and can be used anywhere with attribution.
rtop-vis's home page has more
information and screenshots!
You might also be interested in the sibling projects rtop (CLI version, no GUI, single server) and rtop-bot (Slack and HipChat bot version, on-demand).
rtop-vis is written in go, and requires Go
version 1.2 or higher. To build, go get it:
go get github.com/rapidloop/rtop-vis
You should find the binary rtop-vis under $GOPATH/bin when the command
completes. There are no runtime dependencies or configuration needed.
Pull requests welcome. Keep it simple.
