Problem: history charts report errors

Description: history diagrams within the GridMonitor GUI show no values for a particular parameter, but errors like NOTE: no data for 'memfree'.

Verify that the collector is configured to save the reported parameter to the database. For example, to save the memfree parameter periodically to the database, an entry like

      memfree = {
        save_history = true,
        poll = 600

must be present in the configuration file /etc/pscollect/cluster.conf. How to configure these parameters is described in the section called “Configuring the collector – step 9”.
