Add a panel for tnt_clock_delta panel to cluster overview section.
Add corresponding "delta" label_pairs to Telegraf.
dashboard: add replication status panel
tnt_replication_status was introduced in metrics 0.13.0. This patch adds
replication status timeseries panel to cluster overview section and
corresponding "stream" label pairs to Telegraf.
Timeseries is a base panel since Grafana 8.0. It is possible to set
value mapping in a timeseries panel, which is convenient for replication
status display. There is no way to make a 8.x timeseries panel with
grafana/grafonnet-lib tools for now (7.x subfolder graph
is incompatible), so this patch also introduces a rough draft of a
timeseries panel template.
Grafana requirement was bumped to 8.0.0.
alerts: add replication not running alert
dashboard: add read only status panel
Add master/slave status panel to a cluster overview section.
tnt_read_only metric was introduced in 0.11.0.
Add vinyl regulator blocked writers panel to a vinyl section.
tnt_vinyl_regulator_blocked_writers metric was introduced in 0.13.0.
dashboard: add detailed net requests panels
Add panels for net requests in progress/in stream queue to "Tarantool
network activity" section. Deprecate existing net requests panels
since they are superseded by new ones. (Since new ones are supported in
Tarantool 2.10.0-beta2 or newer, do not remove them yet.) Metrics
were introduced in metrics 0.13.0:
tnt_net_requests_in_progress_total
tnt_net_requests_in_progress_current
tnt_net_requests_in_stream_queue_total
tnt_net_requests_in_stream_queue_current
dashboard: use new metrics instead of deprecated ones
In metrics 0.13.0, the following metrics were deprecated:
tntreplication*_lag
tnt_fiber_count
tnt_space_count
tnt_vinyl_scheduler_dump_count
Instead of them, new metrics were introduced:
tnt_replication_lag
tnt_fiber_amount
tnt_vinyl_tuples
tnt_vinyl_scheduler_dump_total
This patch replaces deprecated metrics with their aliases.
