Monitor the SystemManage Log Files Using CLE and HSS CommandsIntroduction to various log files.Change the Logging Location of atftpdProvides steps to edit the atftpd configuration file and then restart the atftpd service.Check the Status of System ComponentsUse the xtcli status command to check component status.Check the Status of Compute ProcessorsHow to use the xtprocadmin and xtnodestat commands.Monitor the System with the System Environmental Data Collector (SEDC)Introduction to the SEDC.Check Cabinet Cooling Parameters for an Air-Cooled XC SystemApplies to XC-AC systems only. Always do this for a preinstalled system, for a system with newly added hardware, for a system that has just had a fresh install or software update. It is also good practice to periodically check an operational system to verify that cooling parameters are set correctly.Monitor the Health of PCIe ChannelsAbout the xtpcimon command.Examine Activity on the HSS Boot ManagerAbout the xtcli session show command.Poll a Response from an HSS Daemon, Manager, or the Event RouterAbout the xtalive command.Validate the Health of the HSSAbout xtcheckhss and its series of HSS tests.Monitor Event Router Daemon (erd) EventsAbout the xtconsumer command.Monitor Node Console MessagesHow and where console messages are logged.View Component Alert, Warning, and Location HistoryAbout the xtcli comp_hist command.Display Component InformationAbout the xtshow command.Display Alerts and WarningsAbout the xtshow command.Display System Network Congestion Protection InformationAbout the xtcpreport and xtcptop utilities.Clear Component FlagsAbout the xtclear command.Display Error CodesAbout the xterrorcode command.Cray Lightweight Log Manager (LLM)Debug Logging using debugraw and debugmaxcdump and crash Utilities for Node Memory Dump and AnalysisResource Utilization ReportingOverview of RURLinux System Accounting TipsTips for sites using traditional Linux accountingUser Job Performance VariationUnwanted user job runtime variation on XC systems can have multiple causes and solutionsRelated conceptsAbout XC Series System Administration Guide (S-2393)About the Cray Management SystemManage the SystemManage System AccessModify an Installed System
