Build Version Documentation Status Build Status

ISA (Independent Statistics Aggregator) collects node statistics for a cluster of nodes.


  • Can collect many node statistics such as CPU usage, memory usage and disk I/O

  • Easy to setup and flexible node configuration

  • Ensures minimal influence for the node statistics

  • No setup required on the nodes, the statistic management is done centrally


Run the following code in order to install ISA:

pip install isa

Or you can install ISA using

python install

Simple example

Suppose you have two servers. server-a with ip address, username root and password pass123 and you have a second server server-b with hostname, username ubuntu and password test123. This information needs to be specified in a nodes.ini file, so ISA can connect to your servers:

host =
username = root
password = pass123

host =
username = ubuntu
password = test123

Now we have this in place, we can use ISA to monitor the two nodes:

isa /path/to/nodes.ini

If you want to write all results directly to a CSV file, you can use the following snippet:

isa /path/to/nodes.ini --out stats.csv
