NAME
gerrit show-caches - Display current cache statistics.
SYNOPSIS
ssh -p <port> <host> gerrit show-caches [--show-jvm] [--cache <NAME> …]
DESCRIPTION
Display statistics about the size and hit ratio of in-memory caches.
By default, the command displays statistics for all registered caches. Because collecting data for numerous large caches on a busy server can cause delays, the --cache option can be used (one or more times) to limit the output to specific caches.
OPTIONS
- --show-jvm
-
List the name and version of the Java virtual machine, host operating system, and other details about the environment that Gerrit Code Review is running in.
- --show-threads
-
Show detailed counts for Gerrit specific threads.
- --cache <NAME>
-
Show statistics only for the cache called <NAME>. May be supplied more than once to display multiple caches in a single command execution. Cache names are matched case-insensitively against the full registered cache name (including any plugin prefix). Unknown cache names are silently ignored. The summary sections (SSH, tasks, memory, threads, JVM) are not affected by this option.
- --width
- -w
-
Width of the output table.
ACCESS
The caller must be a member of a group that is granted one of the following capabilities:
The summary information about SSH, threads, tasks, memory and JVM are only printed out if the caller is a member of a group that is granted the Administrate Server or Maintain Server capability.
SCRIPTING
Intended for interactive use only.
