172
174 The TIMESPEC in any command line option can be specified in many dif‐
175 ferent formats. It can be just an integer number of seconds, a number
176 plus units (ms/msec/us/usec/s/sec/m/min/h/hr), or an ISO 8601 period
177 specification.
178
180 By default, a certain list of sections are written to the output desti‐
181 nation. The default varies based on the output format - XML includes
182 everything, while other output formats will display less. This list
183 can be modified with the --include and --exclude command line options.
184 Each option may be given multiple times on the command line, and each
185 can give a comma-separated list of sections. The options are applied
186 to the default set, from left to right as seen on the command line.
187 For a list of valid sections, pass --include=list or --exclude=list.
188
190 When run interactively, crm_mon can be told to hide and display various
191 sections of output. To see a help screen explaining the options, hit
192 '?'. Any key stroke aside from those listed will cause the screen to
193 refresh.
194
196 Display the cluster status on the console with updates as they occur:
197 crm_mon
199 Display the cluster status on the console just once then exit:
201 crm_mon -1
203 Display your cluster status, group resources by node, and include inac‐
205 tive resources in the list:
206 crm_mon --group-by-node --inactive
208 Start crm_mon as a background daemon and have it write the cluster sta‐
210 tus to an HTML file:
211 crm_mon --daemonize --output-as html --output-to /path/to/doc‐
213 root/filename.html
214 Start crm_mon and export the current cluster status as XML to stdout,
216 then exit:
217 crm_mon --output-as xml
