Pacemaker - Part of the Pacemaker cluster resource manager
Provides a summary of cluster's current state.
Outputs varying levels of detail in a number of different
formats.
- -I,
--include=SECTION(s)
- A list of sections to include in the output. See `Output Control` help for
more information.
- -U,
--exclude=SECTION(s)
- A list of sections to exclude from the output. See `Output Control` help
for more information.
- --node=NODE
- When displaying information about nodes, show only what's related to the
given node, or to all nodes tagged with the given tag
- --resource=RSC
- When displaying information about resources, show only what's related to
the given resource, or to all resources tagged with the given tag
- -n,
--group-by-node
- Group resources by node
- -r,
--inactive
- Display inactive resources
- -f,
--failcounts
- Display resource fail counts
- -o,
--operations
- Display resource operation history
- -t,
--timing-details
- Display resource operation history with timing details
- -c, --tickets
- Display cluster tickets
- -m,
--fence-history=LEVEL
- Show fence history: 0=off, 1=failures and pending (default without
option), 2=add successes (default without value for option), 3=show full
history without reduction to most recent of each flavor
- -L,
--neg-locations
- Display negative location constraints [optionally filtered by id
prefix]
- -A,
--show-node-attributes
- Display node attributes
- -D,
--hide-headers
- Hide all headers
- -R,
--show-detail
- Show more details (node IDs, individual clone instances)
- --show-description
- Show resource descriptions
- -b, --brief
- Brief output
- -h,
--as-html=FILE
- Write cluster status to the named HTML file. Use
--output-as=html --output-to=FILE
instead.
- -X, --as-xml
- Write cluster status as XML to stdout. This will enable one-shot mode. Use
--output-as=xml instead.
- -s,
--simple-status
- Display the cluster status once as a simple one line output (suitable for
nagios)
- -N,
--disable-ncurses
- Disable the use of ncurses. Use --output-as=text
instead.
- -w, --web-cgi
- Web mode with output suitable for CGI (preselected when run as *.cgi). Use
--output-as=html --html-cgi instead.
- -$, --version
- Display software version and exit
- -V, --verbose
- Increase debug output (may be specified multiple times)
- -Q, --quiet
- Be less descriptive in output.
If this program is called as crm_mon.cgi,
--output-as=html and --html-cgi are automatically added
to the command line arguments.
Time Specification:
The TIMESPEC in any command line option can be specified in many
different formats. It can be an integer number of seconds, a number plus
units (us/usec/ms/msec/s/sec/m/min/h/hr), or an ISO 8601 period
specification.
By default, a particular set of sections are written to the output
destination. The default varies based on the output format: XML includes all
sections by default, while other output formats include less. This set can
be modified with the --include and --exclude command line
options. Each option may be passed multiple times, and each can specify a
comma-separated list of sections. The options are applied to the default
set, in order from left to right as they are passed on the command line. For
a list of valid sections, pass --include=list or
--exclude=list.
When run interactively, crm_mon can be told to hide and show
various sections of output. To see a help screen explaining the options,
press '?'. Any key stroke aside from those listed will cause the screen to
refresh.
Display the cluster status on the console with updates as they
occur:
- crm_mon
Display the cluster status once and exit:
- crm_mon -1
Display the cluster status, group resources by node, and include
inactive resources in the list:
- crm_mon --group-by-node --inactive
Start crm_mon as a background daemon and have it write the cluster
status to an HTML file:
- crm_mon --daemonize --output-as html --output-to
/path/to/docroot/filename.html
Display the cluster status as XML:
- crm_mon --output-as xml
