Basic Commandssetstats (CX series only)Sets statistics loggingDescriptionSyntaxPrerequisitesOptionsThe naviseccli or navicli setstats command sets statistics logging. Ifno optional switches are present, the command returns the currentstate of statistics logging. The SP maintains a log of statistics for theLUNs, disk modules, and storage-system caching that you can turnon and off. When enabled, logging affects storage-systemperformance, so you may want to leave it disabled unless you have areason to monitor performance.The log uses a 32-bit counter to maintain the statistics numbers.When the counter is full, the statistics numbers restart at zero. As aresult, you will see a sudden decrease in a statistics number if youview it shortly before the counter is full and shortly after the counterrestarts at zero. If you want to keep the log turned on for more thantwo weeks, we recommend that you reset the log about every twoweeks, so you know when the numbers start at zero.The command affects only the SP you specify.setstats is used with naviseccli (described on page 37) or navicli(described on page 45) as follows:setstats [-on | -off]For naviseccli, you must have a user account on the storage systemon which you want to execute the command.For navicli, you must have a user entry in the Navisphere agentconfiguration file.-onEnables statistics logging.-offDisables statistics logging.Note: If statistics logging is off, certain options in other commands aredisabled. The options for the other commands specify whether statisticslogging must be on for their options to be valid.OutputThere is no output.
