[Collectl-interest] colmux time format error

Hello,

We are trying to gather detailed CPU usage from a number of machines in our
cluster. In particular, we want to see usage of every individual CPU in a
group of machines.

With collectl, on a single machine, the command we can run is:

   collectl -sC -oT -P

Which gives us 282 columns (the machines have 28 CPU's).

Now we want to run a colmux command to see the idle time of CPU's 0 and 1
on 3 machines. This is columns 10 and 20 ("[CPU:0]Idle%" and
"[CPU:1]Idle%"). The command we use is:

   colmux -addr 'machine-[1-3]' -command "-sC -oT -P" -cols 10,20

This generates the error:

   Minute '60' out of range 0..59 at /usr/bin/colmux line 1699.

The error occurs when parsing the field "lasttime" of a data structure
$hostVars, which has the following content at the time of the error:

{
          'lasttime' => [
                          '',
                          '20160615'
                        ],
          'maxinst' => [
                         -1,
                         0
                       ],
          'lastinst' => [
                          -1,
                          0
                        ],
          'bufptr' => 1
};

I am currently running version "collectl V3.6.9-1 (zlib:2.06,HiRes:1.9725)"
on Debian. Any idea of what may be the problem here?


Thanks in advance,

Hernan
