Re: how many active session?
Another approach is to turn accounting on, and use those records to create the view. We had the same need, and wrote a Rexx program that daily reads those records and generates a timeline using a very basic text format of a bar graph showing exactly when each session was running. We reference this whenever we want to add new nodes, or occassionally revamp the entire schedule, since it shows where our "spikes" and "holes" are. -Original Message- From: "Mr. Lindsay Morris" <[EMAIL PROTECTED]> Sent: Thursday, October 17, 2002 9:17 AM To: VM.MARIST.EDU;.ADSM-L Subject: Re: how many active session? One way to do this is to take periodic "query session" readings and count them. A better way (ours) is to analyze the activity log for session-start and session-end messages (not as easy as it sounds, but do-able). This is better because: 1. It doesn't hammer your TSM server with queries 2. It sees all the fine detail of session activity. When a TSM schedule fires, you may have 50 nodes in session - but only for a minute. 60 seconds later 8 of them are done; two minutes later 25 of the are done. So there's a spike of activity that you'd miss, if you only took a reading once every five minuntes. What good is this detail? Well, when you look at a night's worth, you might see that there's a spike at 8PM, which is mostly done by 8:30. Then there's another spike at 10PM. But from 8:30 to 10:00 PM, nothing much is happening. So you can see that it might be smart to move your 10 PM job up to 8:30, and squeeze your backups into a smaller window. - Mr. Lindsay Morris Lead Architect, Servergraph www.servergraph.com 859-253-8000 ofc 425-988-8478 fax > -Original Message- > From: ADSM: Dist Stor Manager [mailto:ADSM-L@;VM.MARIST.EDU]On Behalf > Of Niklas Lundstrom > Sent: Thursday, October 17, 2002 2:42 AM > To: [EMAIL PROTECTED] > Subject: Re: how many active session? > > > Hello > > The TSM Manager can provide you with this and much more.

Re: how many active session?
Hi Matt I hope I can help with this. It doesn't seem straightforward but one way could be...; select number as sessid,cast(start_time as TIME)as Start,cast(end_time as TIME)as End from summary where activity='BACKUP' AND cast(start_time as DATE)='2002-10-15' This will give you all backup sessions and their start/end time for the date 10/15/2002, but not those that started, say 23:55 the 14th, end ended on the 15th. You might want to put additional checks on this to get all sessions between a start and end-time on two following days. Now, you would have to count the sessions according to start/end-times. I'm sure someone on the list can find a more precise way to count concurrent sessions within a time period. Rgds. Geirr G.

Re: how many active session?
Have you tried scheduling "select count(*) from sessions" every 5 or 10 minutes?
