Using BIGLOSS, but I shouldn't I guess..

I'm using BIGLOSS to send me an email when Smokeping encounters big
packet loss. In cases where we lose a site (someone turned off the
power) I get a BIGLOSS notification. Then a few minutes later I get a
report of it clearing... I guess 100%, 100%, 100% (u,u,u) no longer
counts as bigloss...

So what should I be using to notify me when we get complete drop-out?

TIA,

Eric Brander

This is what I use to monitor hosts being unreachable:

+turnedoff
type = loss
pattern = <100%,==100%,==100%
comment = host not responding

+turnedon
type = loss
pattern = ==100%,==100%,<100%
comment = host back again

I could use only one ==100%, but then I get alarms when the host is just 
quickly restarted, too.

better granularity step 300


hi 

i have the following default configuration at smokeping 

*** Database ***
step     = 300
pings    = 20

i want to have a better granularity, because a break 
of a leased line of even 4 minutes couldn't be detect
in the worst case. 

what happens, if i change to
step     = 30
pings    = 10

would rrdtools show correctly ? 
should i delete the existings rrd-files bevor ? 

best regards 
hans

None of the existing RRDs would notice this, 
but anything new would be created with the 
correct step.  So, you could always move the 
existing files out of the way, let smokeping 
create new ones and then put the old RRD 
data into the newly created RRDs.  Just use 
rrdimport.

Hi,

you have to reconfigure whole database definition

*** Database ***
# every 30 seconds send 10 pings (it is quite lot IMHO)
step     = 30

passing parameters to fping?

Hi.
I have just started trialling smokeping to monitor various customer
satellite connection statistics.
The default timeout of 500msec is causing me headaches though, and I am
getting too many email alerts generated.
I'm getting nice graphs, that make lots of sense, but I am always missing
the first one or two pings, as the rtt can be >800 under perfect
conditions.

I haven't seen in the docs where to pass the parameters to fping,
specifically the -t option.
I need to do a "fping -t 1400"

How can I do this?

Using smokeping 1.38 on debian

Thanks,
Cathal.

Hi Cathal,

I ran into this a while back.  My solutions wasn't the most elegant,
but I just modified the FPing.pm file to manually include that "-t"
argument.  Look for FPing.pm in the probes directory (probably make a
backup copy of the file before you change it).  Look for where "my
 <at> cmd" is defined and add the '-t 1400' inside there (line 111 in
SmokePing v2.0.7).

Re: passing parameters to fping?

Perfect.

I now have the exact behaviour I needed - I now have graphs with green
lines instead of navy or blue...  Looks much prettier, and can be shown
with confidence to the clients.

Appreciated.

Cathal.

Re: passing parameters to fping?

fping's 500ms default timeout was a problem for me,
so I did exactly the same hack.
Additionally, I wanted to fix it "properly",
but on further research abandoned that:
The solution already exists!

See http://smokeping.paracoda.com/doc/smokeping_upgrade.en.html :
"2.0.4 to 2.0.5
FPing
The 'timeout' variable has been removed. It was used to give the fping
command the -t parameter, but as this parameter is only effective in
fping's default mode, while Smokeping uses the counting mode (-c), it
never actually did anything.

I propose to re-introduce that parameter,
as it
a) seems to work with most installations
b) is actually needed with links of latency > 500ms
