+### Generate metrics files
+
+Create a configuration file `/srv/statoolInfos/conf/foo.bar.org.conf`:
+
+```
+conf.probe.types=HttpAccessLog, HttpErrorLog
+conf.probe.httpaccesslog.file=/var/log/apache2/foo.bar.org-access.log*
+conf.probe.httperrorlog.file=/var/log/apache2/foo.bar.org-error.log*
+conf.probe.target=/srv/statoolinfos/well-known/statoolinfos/foo.bar.org.metrics
+
+```
+
+Generate the metric file for the first time:
+
+```
+/srv/statoolinfos/bin/statoolinfos probe -full /srv/statoolinfos/conf/foo.bar.org.conf
+```
+
+Create a cron file to update the metric file everyday:
+
+```
+1 * * * * root /srv/statoolinfos/bin/probe -previousday /srv/statoolinfos/conf/foo.bar.org.conf
+```
