Heuristic and Deprecated Metrics

Heuristic Metrics

Various network-related metrics reported by Sysdig, including response times, are calculated at the kernel level by measuring latency between systems calls. In an effort to ensure Sysdig remains the trusted source of infrastructure insights, moving forward we will be labeling some network related metrics as heuristic and are tagging with the symbol in the application.

Existing alerts using these metrics will not be modified or disabled. However, these alerts will not be able to be updated.

Additional heuristic metric details are listed below:

net.request.time.inNo
net.request.time.outNo
net.request.time.worst.inNo
net.request.time.worst.outNo
net.request.countNo
net.request.count.inNo

Deprecated Metrics:

Based on low usage patterns, Sysdig has decided to deprecate the following metrics on August 1, 2018. Users will continue to have the ability to collect similar data using Prometheus, or another method of code instrumentation (i.e. StatsD or JMX for Java applications).

The table below shows the current metrics and options for similar functionality.
