Subject: Re: [Collectl-interest] colmux time format error
To: Mark Seger <[email protected]>
Hello Mark,
Thanks for the reply! I finally had some time to run the additional tests
you requested. Some comments below...

The machine where I am having this issue is running Debian "jessie/sid".
Kernel is:
Linux spaa-1 3.13.0-85-generic #129-Ubuntu SMP Thu Mar 17 20:50:15 UTC
2016 x86_64 x86_64 x86_64 GNU/Linux
The version of colmux I have installed is "colmux: 4.7.1 (Term::ReadKey:
V2.31 Threads: 1.86)"
When running the command in 'test' mode, the columns 10, 20, 30, ... were
the "%Idle" of the CPU's. Columns 11, 21, 31,... were the "%Total" of the
CPU's.
In both cases, the commands give this error all the time (not an
intermittent error). One or two "-1" rows appear, followed by the message:
Minute '60' out of range 0..59 at /usr/bin/colmux line 1699.
What you didn't say is does this fail all the time or intermittently. If

The error occurs every time I try this command.

I am gathering the output of collectl from all the machines into an NFS
directory. All the machines in the cluster have /var/log/collectl
symlinked to /nfs/mnt/path/to/collectl
If I run the command via replay, it doesn't :
colmux -addr 'spaa-[1-3]' -command "-sC -oT -P -p
'/nfs/mnt/path/to/collectl/*20160621*raw.gz'" -cols 11,21 | less
However, every row the 3 machines all have the same values for CPU0 and
CPU1. Something like:
#Time spaa-1 spaa-2 spaa-3 | spaa-1 spaa-2 spaa-3
...
1 1 1 | 3 3 3
0 0 0 | 11 11 11
...
and since this is a playback command, you can use time ranges as well to

Thanks Mark, I will send a copy of the raw files in a private email.
