[2011/07/15 10:41:26] <M0NSA> mike and cmalton - cacti or mrtg?
[2011/07/15 10:46:07] <cmalton> rtg!
[2011/07/15 10:46:12] <cmalton> not mrtg
[2011/07/15 10:46:14] <cmalton> rtg!
[2011/07/15 10:46:34] <cmalton> mrtg & cacti have some interesting load average problems
[2011/07/15 10:46:47] <cmalton> particularly when you're monitoring 600 odd interfaces
[2011/07/15 10:47:06] <cmalton> or in mike's case, 120000!
[2011/07/15 10:47:16] <cmalton> (or whatever it was)
[2011/07/15 10:47:26] <cmalton> M0NSA: ^^
[2011/07/15 10:47:40] <M0NSA> ok
[2011/07/15 10:48:05] <M0NSA> and i just want something simple to setup as POC on out LAN
[2011/07/15 10:48:37] <M0NSA> the "key" feature being that it must run on windows...
[2011/07/15 10:48:55] <cmalton> M0NSA: I'm sure we can organise that for rtg
[2011/07/15 10:49:08] <M0NSA> hmm
[2011/07/15 10:49:23] <cmalton> cacti on windows is asking for trouble
[2011/07/15 10:49:31] <cmalton> you do have a MySQL server handy right?
[2011/07/15 10:49:58] <cmalton> with an unbounded amount of disk space
[2011/07/15 10:50:21] <M0NSA> i have no hardware atm
[2011/07/15 10:50:33] <M0NSA> this is a POC i want to chuck together to show what can be done
[2011/07/15 10:50:40] <cmalton> hmm
[2011/07/15 10:50:43] <cmalton> ok
[2011/07/15 10:50:50] <M0NSA> so that I can get hardware/access to a server or VM that we have available
[2011/07/15 10:51:16] <cmalton> so if it's a little hacky, is that a problem?
[2011/07/15 10:51:58] <cmalton> so you want something you can POC in a virtual environment?
[2011/07/15 10:52:55] <M0NSA> possibly
[2011/07/15 10:53:01] <M0NSA> or on a spare server
[2011/07/15 10:53:05] <cmalton> ok
[2011/07/15 10:53:30] <M0NSA> basically, if I want to do this, i need to show the benfits of having monitoring
[2011/07/15 10:53:36] <cmalton> how quickly (and don't say yesterday)?
[2011/07/15 10:53:45] <M0NSA> I know what they are, but showing to boss pretty graphs he can show to CTO
[2011/07/15 10:53:54] <M0NSA> by September the 24th ;)
[2011/07/15 10:53:58] <M0NSA> no rush on it
[2011/07/15 10:54:07] <M0NSA> it's just a little side project i have
[2011/07/15 10:54:11] <M0NSA> or rather want to do
[2011/07/15 10:54:38] <cmalton> ok - bear with me :P
[2011/07/15 10:55:12] <M0NSA> kk, ty - i was just after a recommendation between the two as they are both windowsable easily
[2011/07/15 10:55:43] <cmalton> cacti is windowsable, but can be a right pigs ear to get running
[2011/07/15 10:55:52] <cmalton> took me nearly 3-4 weeks
[2011/07/15 10:56:01] <cmalton> even following their guide
[2011/07/15 10:56:06] <M0NSA> ah
[2011/07/15 10:56:18] <cmalton> mrtg I believe is perl-based
[2011/07/15 10:56:25] <cmalton> and perl on windows is fun
[2011/07/15 10:56:52] <M0NSA> hmm
[2011/07/15 10:56:56] <cmalton> and for anything more than about 10-15 interfaces is likely to be interesting on CPU load
[2011/07/15 10:57:21] <cmalton> the activestate perl implementation is a disaster!
[2011/07/15 10:57:28] <cmalton> when it comes to efficiency
[2011/07/15 10:58:42] <mike> If you want a demonstration of what can be done elsewhere with RTG you can have a browse through the following links:
[2011/07/15 11:01:08] <M0NSA> ta mike
[2011/07/15 11:08:46] <mike> M0NSA the only downside is I don't know how well it would run on Windows, but it works very well on Linux (I'm causing iptables issues)
[2011/07/15 11:09:15] <M0NSA> or rather, our provider
[2011/07/15 11:09:22] <M0NSA> so we could have a consistent feel
[2011/07/15 11:10:08] <mike> Depending on what you're wanting to graph the other thing to look at is munin - We've started playing with it for unix system stat collection
[2011/07/15 11:10:09] <M0NSA> mm
[2011/07/15 11:11:10] <M0NSA> what i am interested in for the moment is HP procurve switches
[2011/07/15 11:13:05] <cmalton> mike: something just happened to your graphs
[2011/07/15 11:13:14] <mike> I kicked rtg
[2011/07/15 11:13:20] <cmalton> lol
[2011/07/15 11:13:24] <cmalton> it woke up
[2011/07/15 11:13:43] <M0NSA> cmalton - we have one of the big chassis switches plus a load or 24 and 48 ports
[2011/07/15 11:13:47] <mike> where kicked == pkill ;)
[2011/07/15 11:13:59] <cmalton> M0NSA: oh good luck
[2011/07/15 11:14:14] <mike> In terms of normall polling for stats the HP's are ok.
[2011/07/15 11:14:22] <mike> We've got quite a lot of them
[2011/07/15 11:14:48] <cmalton> hmm
[2011/07/15 11:14:57] <cmalton> ok mike, maybe it's the model we have
[2011/07/15 11:15:41] <cmalton> Part code: 1800-24G (J9028A
[2011/07/15 11:15:55] <M0NSA> cmalton - they are the low end carp
[2011/07/15 11:16:02] <cmalton> so 1800s?
[2011/07/15 11:16:09] <mike> ok maybe we don't have so many now but we used to have a lot.
[2011/07/15 11:16:25] <M0NSA> i have one sat to my left here which we got rid of - low throughput but all gig ports
[2011/07/15 11:16:41] <mike> we had 2650's, 2848's etc so not so low end
[2011/07/15 11:16:49] <cmalton> yeah
[2011/07/15 11:17:02] <cmalton> M0NSA: Are your ones 1800 series?
[2011/07/15 11:17:11] <M0NSA> no, we had a couple for a POC
[2011/07/15 11:17:12] <cmalton> best bet is to fire up a linux vm (if such thing exists)
[2011/07/15 11:17:36] <cmalton> and snmpwalk -v2c -c public <IP> > /dev/null (and time it)
[2011/07/15 11:19:22] <M0NSA> we use 2610s, 5308xl, etc
[2011/07/15 11:19:43] <cmalton> ok
[2011/07/15 11:19:49] <mike> cmalton: if you're going to do that test it's best to just limit it to the interfaces table.
[2011/07/15 11:19:54] <cmalton> true
[2011/07/15 11:19:59] <M0NSA> and 2626s predominantly
[2011/07/15 11:19:59] <cmalton> IF-MIB::*
[2011/07/15 11:20:19] <mike> Different devices have different things available in snmp so might take longer but the actual speed is quite quick
[2011/07/15 11:20:24] <cmalton> but I've never quite got my head around walking IF-MIB:: so I always convert it to numeric
[2011/07/15 11:20:38] <M0NSA> mm, well, i have a linux desktop VM now
[2011/07/15 11:20:44] <M0NSA> but SNMP is disabled on all our switches
[2011/07/15 11:20:46] <cmalton> cool - well
[2011/07/15 11:20:53] <cmalton> you'll just have to turn it on :P
[2011/07/15 11:20:57] <M0NSA> and I am NOT going to enable it just yet
[2011/07/15 11:21:11] <cmalton> find a switch you're not using
[2011/07/15 11:21:14] <cmalton> and use that as test :P
[2011/07/15 11:21:25] <cmalton> you said you had spares :P
[2011/07/15 11:21:30] <M0NSA> only switch we are not using atm is the 1800...
[2011/07/15 11:21:48] <cmalton> it's still doable
[2011/07/15 11:22:28] <M0NSA> mm, just need to talk to network admin and someone else before embarking on it
[2011/07/15 11:23:49] <cmalton> sure
[2011/07/15 11:24:46] <M0NSA> mm
[2011/07/15 11:52:49] <mike> RTG also has the nice one of collecting UCast packets. Which is gives some really nice spikes when someone tries attacking us.
[2011/07/15 11:53:20] <cmalton> mike: Presumably that happens not infrequently
[2011/07/15 12:11:27] <cmalton> ah kk

[2011/07/15 20:33:21] <cmalton> mike, you'll like this one.  HeliosFA was on a hill near Tring, talking to me, on DA!
[2011/07/15 20:34:18] <cmalton> distance of ~ 52 miles!
[2011/07/15 20:34:31] <cmalton> and we could still have a conversation!
[2011/07/15 20:37:39] <mike> I used to regularly do 30+ miles on a handy on 2m
[2011/07/15 20:38:12] <mike> I was in somerset the repeater was in wales.
[2011/07/15 20:40:23] <cmalton> impressive
[2011/07/15 20:40:30] <cmalton> Graeme had to put out 25W
[2011/07/15 20:40:34] <cmalton> to get anywhere close
[2011/07/15 20:41:01] <mike> actually more like 40-50 miles for BC
[2011/07/15 20:41:57] <mike> I was operating from near Yeovil in somerset. The local repeater was WR at about 20 miles, BC was the next closest
[2011/07/15 20:42:06] <mike> and all I had was a handy with 5w
[2011/07/15 20:42:11] <cmalton> impressive
[2011/07/15 20:42:31] <cmalton> from where I am in Essex, I can get DA, and that's it on 10W
[2011/07/15 20:42:53] <mike> I've worked SN from here on a Handy as well.
[2011/07/15 20:43:13] <cmalton> I should be able to get NL
[2011/07/15 20:43:16] <cmalton> but I don't know
[2011/07/15 20:43:18] <mike> I chatted to a friend who was on the outskirts of london via SN when I was a ug
[2011/07/15 20:43:54] <cmalton> well, we'll see
[2011/07/15 20:43:57] <cmalton> I've tuned to NL
[2011/07/15 20:44:02] <cmalton> see if I get the pips
