top commands time+

[Kupen]

Hello,

Can somebody help me with top column TIME+ (second from left). On my box, there is values like 12786:26 (part of them copied above).

10955 postgres 21 0 58496 41m 36m R 30.2 0.2 4326:43 postmaster
19105 postgres 25 0 58496 41m 36m R 28.9 0.2 2389:22 postmaster
13587 postgres 25 0 57324 40m 36m R 27.6 0.2 12786:26 postmaster

What does this mean? I used to know 12:01.10

My box is running CentOs5.4

Thanks,

I ps my processes and cannot identify correct one, but it seems that 12345:48 means 12345 minutes and 48 seconds?

I'm not sure .Please let us know ,what are trying to achieve ?

From "man top"

l: TIME -- CPU Time
Total CPU time the task has used since it started. When ’Cumulative
mode’ is On, each process is listed with the cpu time that it and
its dead children has used. You toggle ’Cumulative mode’ with ’S’,
which is a command-line option and an interactive command. See the
’S’ interactive command for additional information regarding this
mode.

m: TIME+ -- CPU Time, hundredths
The same as ’TIME’, but reflecting more granularity through hun-
dredths of a second.

Hi,

I noticed that on one of our server there are tens of processess with big amount of TIME+ on top. I tried to find our what they are. Something to do with postgres database.

I have previously not seen time+ times like this and now I try to find out, can I just kill them.

Thanks!

does all other process in top command has same time format? are you sure postgres is not needed by any application ? This thread says minutes:second format for top command.

yeps it seems. that all are in same format, except which has run only a few seconds they are like 00:05.10

Out web-software are using postgres db, but all transactions which has been run over 10 minutes are not valid!
