    Istio metrics

    Cloud Monitoring supports the metric types from Cloud Service Mesh and Istio on Google Kubernetes Engine services listed in this document.

    • For a general explanation of the entries in the tables, including information about values like DELTA and GAUGE , see Metric types .

      To chart or monitor metric types with values of type STRING , you must use Monitoring Query Language (MQL), and you must convert the value into a numeric value. For information about MQL string-conversion methods, see String .

    • For information about the units used in the metric lists, see the unit field in the MetricDescriptor reference.

    • For information about statements of the form “Sampled every x seconds” and “After sampling, data is not visible for up to y seconds”, see Additional information: metadata .

    • The resource-hierarchy level tells you if the metric is written at the project, organization, or folder level(s). When the level is not specified in the metric descriptor, the metric writes at the project level by default.

    • For information about the meaning of launch stages such as GA (General Availability) and BETA (Preview), see Product launch stages .

    Metrics from Istio . Launch stages of these metrics: ALPHA BETA

    The "metric type" strings in this table must be prefixed with istio.io/ . That prefix has been omitted from the entries in the table. When querying a label, use the metric.labels. prefix; for example, metric.labels. LABEL =" VALUE " .
