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.

199 tive resources in the list:

202 Start crm_mon as a background daemon and have it write the cluster sta‐
204 tus to an HTML file:
205 crm_mon --daemonize --output-as html --output-to /path/to/doc‐
207 root/filename.html
208 Start crm_mon and export the current cluster status as XML to stdout,
210 then exit:
