grafana-pcp v3.0.0

3.0.0 (2020-11-23)

Highlights of v3.0

• redis: support for Grafana Alerting
• redis: full-text search in metric names, descriptions, instances
• vector: support derived metrics, which allows the usage of arithmetic operators and statistical functions inside a query (pmRegisterDerived(3))
• vector: configurable hostspec (access remote PMCDs through a central pmproxy)
• vector: automatically configure the unit of the panel
• dashboards: detect potential performance issues and show possible solutions with the checklist dashboards, using the USE method
• dashboards: new MS SQL server dashboard (Louis Imershein)
• dashboards: new eBPF/BCC dashboard
• dashboards: new container overview dashboard with CGroups v2

Breaking Changes in v3.0

• dashboards: All dashboards are now located in the Dashboards tab at the datasource settings pages and are not imported automatically
• redis: Using label_values(metric, label) in a Grafana variable query is deprecated due to performance reasons. label_values(label) is still supported.

New Features

• redis: added instance.name and dashboard variables support in query editor
• redis: heatmap support
• dashboards: updated PCP Redis Metric Preview dashboards: added metric drop-down
• dashboards: added MS SQL server dashboard for Vector (Louis Imershein)
• chore: sign plugin

Enhancements / Bug Fixes

• redis: implement workaround if two values for the same instance and timestamp are received
• redis: send one instance labels request instead of one per instance
• redis: refresh instances only once per series
• redis: improved error messages
• vector: (internal) option to disable time utilization conversion
• vector: show error message when access mode is set to server & url override is set
• vector: disable redis backfill for now (pmseries and pmapi instance id's don't match)
• bpftrace: interpret all fields of CSV output as strings
• dashboards: moved dashboards to the datasource level: dashboards of interest can be imported using the dashboards tab of each datasource settings page
• dashboards: fix KB/s unit in dashboards, should be KiB/s
• dashboards: add installation instructions to BCC and bpftrace dashboards
• dashboards: update titles and add units to checklist dashboards
• search: fix datasource detection
• search: propagate error messages to the user
• poller: use timeout instead of interval to prevent overlapping timers
• poller: deregister targets immediately if endpoint changed
• chore: update build dependencies
• test: add unit tests to all datasources
• test: add End-to-End tests
• docs: update authentication guide to use scram-sha-256

grafana-pcp v3.0.0-beta1

3.0.0-beta1 (2020-10-12)

New features

• redis: support for Grafana Alerting
• redis: full-text search in metric names, descriptions, instances
• vector: support derived metrics, which allows the usage of arithmetic operators and statistical functions inside a query, see pmRegisterDerived(3)
• vector: checklist dashboard: detects potential performance issues and shows possible solutions to resolve them
• vector: set background metric poll interval according to current dashboard refresh interval, do not stop polling while in background
• vector: automatically configure the unit of the panel

Enhancements / Bug Fixes

• build: convert dashboards to jsonnet/grafonnet
• all: use latest Grafana UI components based on React (Grafana previously used Angular)

Redis datasource installation

Unfortunately it is not possible to sign community plugins at the moment. Therefore the PCP Redis datasource plugin needs to be allowed explicitely in the Grafana configuration file:

allow_loading_unsigned_plugins = pcp-redis-datasource

Restart Grafana server, and check the logs if the plugin loaded successfully.

Deprecated features

• redis: Using label_values(metric, label) in a Grafana variable query is deprecated due to performance reasons. label_values(label) is still supported.
