(Legacy) Heuristic and Deprecated Metrics

Various network-related metrics reported by Sysdig, including response times, are calculated at the kernel level by measuring latency between systems calls. In order to provide infrastructure insights, Sysdig labels some network related metrics as heuristic.

Heuristic Metrics

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

Additional heuristic metric details are listed below:

Metric	Set New Alerts
net.http.request.time	Yes
net.http.request.count	Yes
net.http.error.count	Yes
net.sql.request.time	Yes
net.sql.request.count	Yes
net.sql.error.count	Yes
net.mongodb.request.time	Yes
net.mongodb.request.count	Yes
net.mongodb.error.count	Yes
net.request.time.file.percent	Yes
net.request.time.local.percent	Yes
net.request.time.net.percent	Yes
net.request.time.nextTiers.percent	Yes
net.request.time.processing.percent	Yes
net.request.time	No
net.request.time.in	No
net.request.time.out	No
net.request.time.worst.in	No
net.request.time.worst.out	No
net.request.count	No
net.request.count.in	No

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.

Current Metric	Alternative Starting August 1, 2018
capacity.estimated.request.stolen.count	Create your application metrics using Prometheus, StatsD or JMX for Java applications.
capacity.estimated.request.total.count
capacity.stolen.percent
capacity.total.percent
capacity.used.percent
net.request.time.file
net.request.time.local
net.request.time.net
net.request.time.nextTiers
net.request.time.processing
net.sql.request.time.worst	Max aggregation (net.sql.request.time)
net.mongodb.request.time.worst	Max aggregation (net.mongodb.request.time)
net.http.request.time.worst	Max aggregation (net.http.request.time)
