Metrics reference

This chapter explains how to read the generated metrics reference. Topics: 6.1 Where the reference is · 6.2 How to read a metric group · 6.3 Naming conventions

6.1 Where the reference is

The plug-in’s metric documentation is generated from the plug-in’s own target metadata, for the exact build you deploy, rather than written by hand — so it cannot drift from what the plug-in actually collects.

For this build it is the reference below, shipped alongside this guide. It covers all 116 metric groups: 105 on MySQL Database, 8 on MySQL Cluster and 3 on MySQL ClusterSet, each with its collection schedule, its columns, their display labels and units, and the default thresholds that ship. Where this guide and the reference differ on a column name, a unit or a threshold, the reference is authoritative (1.4).

Note: The reference accompanies this guide: in the repository as user-guide-metrics-reference.md, on the documentation site as metrics-reference.md. Either way, use the copy that matches the build you are running.

6.2 How to read a metric group

Every entry in the reference has the same shape, so once you can read one you can read all of them.

The heading gives the group’s display name, its internal name in parentheses — the name EM CLI, thresholds and the metric browser use — and its collection schedule, for example collected every 5 Min. One sentence underneath says what the group collects and where the values come from. Then comes the column table:

Column	What it tells you
Column	The column’s internal name, in the form EM CLI and threshold commands take. A `(key)` marker means the column is part of the group’s key, so the group returns one row per distinct key value — per channel, per member, per table, per digest — rather than a single row. A group with no key column returns exactly one row per collection.
Label	The display name shown in the console.
Unit	The unit Enterprise Manager labels the value with, for example `MICROSEC`, `BYTE`, `SECOND` or `PERCENTAGE`. `NA` means the value carries no unit — a count, a state or a string.
Warning / Critical	The default threshold that ships for the column, with its operator. A blank cell means no default threshold, which is the normal case: 19 curated thresholds ship (7.1), and the reference also shows the three availability `Status` conditions, so 22 columns in the reference tables carry a default. A blank cell is not an omission and it does not stop you setting your own (7.2).

Groups marked configuration snapshot in their heading behave differently from the rest. They collect on a 24-hour schedule into Enterprise Manager’s configuration history rather than into the metric tables, which is what makes a MySQL server’s settings comparable over time and against other servers under Enterprise → Configuration, and what the compliance rules in chapter 9 evaluate. They carry no thresholds and raise no alerts, and a (key) column in one of them means the snapshot holds several rows — one per account, for example — rather than one row of settings.

6.3 Naming conventions

Column names follow a few conventions consistently, so the name usually tells you what kind of number you are looking at.

Suffix or pattern	Meaning
`_delta`	The difference since the previous collection. The server counter behind the column is cumulative since startup; the `_delta` column reports the activity in the interval instead, which is what a threshold can be set against.
`_pct`	A percentage, on a 0–100 scale.
`_rate`	A ratio expressed as a percentage — the buffer pool hit rates, for example, which the plug-in normalizes to percent at one decimal place. It is not a per-second figure.
`_per_sec`	A per-second rate.
`_us`	Microseconds. Statement and wait latencies are reported in microseconds throughout.
`d_` prefix	A per-interval delta on the wait and statement digest groups, the keyed equivalent of `_delta`.
`*Live` group	A real-time mirror of the configuration snapshot group of the same name — the same server variables, read on demand for the console’s configuration side panels (5.1) instead of on the daily configuration schedule. Same values, different freshness.

Note: The replication metric group reports two different boolean vocabularies. replica_io_running returns Yes or No, while replica_sql_running returns true or false. The shipped thresholds match those forms exactly (7.1); a custom threshold, compliance rule or script that reads both columns must not assume a single format.

Generated from the plug-in’s target metadata for build 24.1.9.9.0. Each metric group lists its columns, display labels, units, and the default warning/critical thresholds that ship (blank = no default threshold). Configuration snapshots are RAW metrics collected for configuration history; they do not carry thresholds. See the User Guide, chapter 6, for how to read this file.

`consistency_after_termination_time_us`	Consistency Wait Time (After Termination)	MICROSEC

Backup Source (`BackupSource`) — collected every 15 Min

Which cluster member the most recent successful backup was taken from, and whether that member is still online in the group. Reads MySQL Enterprise Backup’s mysql.backup_history joined against Group Replication membership; Percona XtraBackup backups are reported without member identity because PERCONA_SCHEMA.xtrabackup_history does not record it.

Column	Label	Unit	Warning
`source_uuid`	Source Member UUID	NA
`source_member`	Source Member	NA
`source_state`	Source Member State	NA
`source_offline`	Backup Source Offline	NA	> 0
`last_success_end_time`	Last Successful Backup End Time	NA
`tool`	Backup Tool	NA

MySQL InnoDB ClusterSet (`ip_mysql_clusterset_beta`)

Response (`Response`) — collected every 1 Min

Availability. EM derives the target’s Up/Down state from the Status column; a Status below 1 raises the target-down event.

Column	Label	Unit	Warning	Critical
`Status`	Status (up/down)	NA		< 1

ClusterSet Health (`ClusterSetHealth`) — collected every 5 Min

Single-row alertable ClusterSet health composite. Runs mysqlsh AdminAPI (clusterSet.status) from the agent host; requires mysqlsh on the agent’s PATH. dr_promotion_ready is 1 when the ClusterSet can be failed over and 0 when it cannot; under a network partition the Shell reports HEALTHY with the replication channel CONNECTING, which this metric surfaces as not promotion-ready.

Column	Label	Unit	Critical
`health_source`	Health Source	NA
`fallback_reason`	Fallback Reason	NA
`primary_healthy`	Primary Healthy	NA
`replica_clusters_healthy`	Replica Clusters Healthy	NA
`replication_channel_ok`	Replication Channel OK	NA
`gtid_lag`	GTID Lag	NA
`errant_gtid_count`	Errant GTID Count	NA
`dr_promotion_ready`	DR Promotion Ready	NA	< 1
`replica_cluster_count`	Replica Cluster Count	NA
`domain_name`	Domain Name	NA
`primary_cluster`	Primary Cluster	NA
`global_primary_instance`	Global Primary Instance	NA
`status`	Status	NA
`status_text`	Status Text	NA

ClusterSet Clusters (`ClusterSetClusters`) — collected every 5 Min

Per-cluster ClusterSet detail, keyed by cluster name — role, status, replication status, and GTID consistency versus the primary. Runs mysqlsh AdminAPI (clusterSet.status) from the agent host; requires mysqlsh on the agent’s PATH.

Column	Label	Unit
`cluster_name` (key)	Cluster	NA
`cluster_role`	Role	NA
`global_status`	Global Status	NA
`cluster_set_replication_status`	ClusterSet Replication Status	NA
`transaction_set_consistency_status`	Transaction Set Consistency	NA
`missing_gtid_count`	Missing Transactions	NA
`errant_gtid_count`	Errant Transactions	NA
`primary_instance`	Primary Instance	NA
`missing_gtid_set`	Missing GTID Set	NA
`errant_gtid_set`	Errant GTID Set	NA
