On theMonitoringpage, the metrics charts show information that can
help you monitor plugin performance.
To view the metrics for plugin lifecycle operations, select values from theOperation filterlist. By default, the valuesHTTP request headerandHTTP response headerare selected.
To view the metrics for a specific plugin version, select a value from thePlugin version filterlist. By default, metrics are displayed for
all versions.
To change the period for which you want to view the data, either select a
predefined period from the time selector or clickCustomand define a
start and end time. By default, the selector is set to1 day.
Plugin metrics for Service Extensions
You can monitor the following metrics for plugins from the
Service Extensions perspective. These metrics have the prefixnetworkactions.googleapis.com/wasm_plugin/. The prefix is omitted from the entries in the table.
Metric type
Display name Kind, Type, Unit Description
invocation_count
Wasm plugin invocation count DELTA, INT64, 1 The number of invocations of the plugin over the selected time
span. Each plugincallbackinvocation counts as a separate plugin invocation.
invocation_latencies
Wasm plugin invocation latency DELTA, DISTRIBUTION, us The local execution time, in milliseconds, of the plugin. The
metric includes label-delineated entries for eachcallback.
cpu/usage_times
Wasm plugin normalized CPU usage DELTA, DISTRIBUTION, us{CPU} The CPU usage time of plugin invocations, in microseconds.
memory/bytes_used
Wasm plugin memory usage GAUGE, DISTRIBUTION, By Total memory allocated by Wasm plugin VMs, in bytes.
Plugin metrics for Media CDN
You can monitor the following metrics for plugins from the
Media CDN perspective. The metric type
strings follow this prefix:edgecache.googleapis.com/edge_cache_route_rule/network_actions/.
The prefix is omitted from the entries in the table.
Metric type
Display name Kind, Type, Unit Description
wasm_action_invocation_count
Service Extensions invocation count DELTA, INT64, 1 The number of Service Extensions invocations
handled by Media CDN over the selected time span.
wasm_action_invocation_latencies
Service Extensions invocation latency DELTA, DISTRIBUTION, us The total time, in milliseconds, that Media CDN
takes to dispatch and execute the plugin. The metric includes
label-delineated entries for Service Extensionscallbacks.
