154

TIME SPECIFICATION

156       The  TIMESPEC  in any command line option can be specified in many dif‐
157       ferent formats.  It can be just an integer number of seconds, a  number
158       plus  units  (ms/msec/us/usec/s/sec/m/min/h/hr),  or an ISO 8601 period
159       specification.
160

EXAMPLES

162       Display the cluster status on the console with updates as they occur:
163
164              crm_mon
165
166       Display the cluster status on the console just once then exit:
167
168              crm_mon -1
169
170       Display your cluster status, group resources by node, and include inac‐
171       tive resources in the list:
172
173              crm_mon --group-by-node --inactive
174
175       Start crm_mon as a background daemon and have it write the cluster sta‐
176       tus to an HTML file:
177
178              crm_mon --daemonize --output-as html  --output-to  /path/to/doc‐
179              root/filename.html
180
181       Start  crm_mon  and export the current cluster status as XML to stdout,
182       then exit:
183
184              crm_mon --output-as xml
