Troubleshooting

. When did this issue begin occurring? - Does this time and date coincide with any other events? . How often does it occur? - Is is continuous or off and on? - If off and on, is there any pattern to the events? - Are there any other events that coincide when the issue occurs? Like backups or peak business hours? . What is the time stamp of the last time this occurred? - Does this time and date coincide with any other events? . Is it the entire system or is it a particular subsystem/application? For example, is the slowness at the console as well as over ssh or is it specific to an action, is it specific to an application, etc? . Does this same performance impact occur when all 3rd party or only certain 3rd party applications are disabled? . Where and how is the performance impact being observed? . Can a complete description of what the performance is supposed be provided? In particular how the expected performance was measured, what the results were, etc . What is the present status of the system? Is it working normally? or is it experiencing any issues? . What type of workload is this system responsible for ordinarily? I.E. Does it host a database, fileserver, or other application? . Were there any power or networking outages reported near the time that this issue occurred? . Do you know of any CPU and/or memory intensive process that could have been running on the system at the time of the issue? . Were there any messages on the console at the time of the issue? If so, can they be provided to the case in their entirety? . Is this system part of a cluster? . Does the issue cause the system to have a vmcore generated? . Were there any recent changes to the hardware/firmware/software recently? If so, when and what was changed?


Please clarify the issue "servers running slow" - Is some process not completing on time? - Are commands issued to the system taking a long time to complete? What benchmark or comparison do you have to indicate that this is a problem? When did this issue begin occurring? Were any hardware or software changes or upgrades made before this issue began? Has the workload on the system changed at all? Is the issue persistent, repeatable, or random? Do you have any other data that may help in our investigation, including screenshots, comparisons indicating the performance loss, etc.
