[smokeping-users] Scalability

[Colin Horsington]

Hi all,

I have a server with 2480 hosts configured heirachically in four levels.

i.e. /dsl/region/town/dsl_user

I previously had the same config runnning for several hundred hosts.
However when I now start smokeping it seems to exit after a minute or two.
When I run it in debug mode the following output is recorded:

#(root)-(0)-(#####) -=> /usr/sbin/smokeping --debug
/var/lib/smokeping/DSL
### fping seems to report in 1 miliseconds
### Compiling
 sub { my $d = shift; my $y = $d->{rtt};
return 0 unless 9 <= scalar @$y ;
return 0 unless defined $y->[-9] and $y->[-9] < 0.01;
return 0 unless defined $y->[-8] and $y->[-8] < 0.01;
return 0 unless defined $y->[-7] and $y->[-7] < 0.01;
return 0 unless defined $y->[-6] and $y->[-6] < 0.01;
return 0 unless defined $y->[-5] and $y->[-5] < 0.01;
return 0 unless defined $y->[-4] and $y->[-4] < 0.1;
return 0 unless defined $y->[-3] and $y->[-3] > 0.1;
return 0 unless defined $y->[-2] and $y->[-2] > 0.1;
return 0 unless defined $y->[-1] and $y->[-1] > 0.1;
return 1; }
### Compiling
 sub { my $d = shift; my $y = $d->{loss};
return 0 unless 7 <= scalar @$y ;
return 0 unless defined $y->[-7] and $y->[-7] == 0;
return 0 unless defined $y->[-6] and $y->[-6] == 0;
return 0 unless defined $y->[-5] and $y->[-5] == 0;
return 0 unless defined $y->[-4] and $y->[-4] == 0;
return 0 unless defined $y->[-3] and $y->[-3] > 4;
return 0 unless defined $y->[-2] and $y->[-2] > 4;
return 0 unless defined $y->[-1] and $y->[-1] > 4;
return 1; }
Launched successfully
FPing: probing 2480 targets
ERROR:
'/var/lib/smokeping/DSL/NSW/BOWRAL/StewartBarlenHireSouthern_Rubus_024861775
3.rrd' is not an RRD file

If I remove this rrd, and rerun smokeping it complains about another RRD...I
have tried removing all the RRDs and restarting smokeping but it dies.

Any ideas?

Thanks,

Colin
