Log your system telemetry to AppInsights custom metrics using the psutil library in Python. To visualize the telemetry data you can use Kusto Query Language in AppInsights.
You can install appinsights-telemetry-logger utility directly from Github.
$ pip install git+https://github.com/chaosmail/appinsights-telemetry-python#appinsights-telemetry-python.egg
$ appinsights-telemetry-logger -hBy default, the telemetry logger only logs the CPU utilization in percent. However, many other metrics exposed by psutil can be logged as well using the apppropriate command line options.
usage: appinsights-telemetry-logger
[-h] -k APPINSIGHTS_KEY [-c CPU_INTERVAL] [-l LOG_INTERVAL]
[-p] [--percpu] [--perdisk] [--path PATH] [--pernic]
[--cpu-times] [--cpu-stats] [--virtual-memory] [--swap-memory]
[--disk-usage] [--disk-io-counters] [--net-io-counters]
optional arguments:
-h, --help show this help message and exit
-k APPINSIGHTS_KEY, --appinsights-key APPINSIGHTS_KEY
-c CPU_INTERVAL, --cpu-interval CPU_INTERVAL
-l LOG_INTERVAL, --log-interval LOG_INTERVAL
-p, --print
--percpu
--perdisk
--path PATH
--pernic
--cpu-times
--cpu-stats
--virtual-memory
--swap-memory
--disk-usage
--disk-io-counters
--net-io-counters
Log the CPU utilization, disk usage and virtual memory consumption every 10 seconds.
appinsights-telemetry-logger \
--appinsights-key <insert instrumentation key> \
--log-interval 10 \
--disk-usage \
--virtual-memory To visualize metrics in AppInsights go to the Analytics pane and type your query.
Here is an example visualizing percentage of CPU utilization, memory consumption and used disk space.

| sort by timestamp desc nulls first
