| == NAME |
| gerrit show-caches - Display current cache statistics. |
| |
| == SYNOPSIS |
| [verse] |
| -- |
| _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: |
| |
| * link:access-control.html#capability_viewCaches[View Caches] |
| * link:access-control.html#capability_maintainServer[Maintain Server] |
| * link:access-control.html#capability_administrateServer[Administrate Server] |
| |
| 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 link:access-control.html#capability_administrateServer[Administrate |
| Server] or link:access-control.html#capability_maintainServer[Maintain |
| Server] capability. |
