Zabbix IT Services feature set
by Graham Johnston 18 Jul '17

18 Jul '17

Hi, We have the Zabbix IT Services (running on Zabbix 3.2) configured for some test groups. It usually returns good data but occasionally it seems that one service group or trigger will get stuck in an alerting state and provide an incorrect SLA. This can occur if the trigger has changed to a problem state and then back to OK but the IT services doesn't reflect that change. It will occur where the top level group will show as having 100% problem time and the sub groups and items either have no problem time or such a small amount that it wouldn't indicate 100% problem time. We have it built with some groups under root, some sub groups and items and the items will have a trigger associated with those items. We followed this article to the best of our knowledge: https://www.zabbix.com/documentation/3.2/manual/it_services For Example: |Data Center |-Core1 |--Core1 - ICMP - Trigger |-Core2 |--Core2 - ICMP - Trigger Each subitem is a child of the item above it. We haven't configured any dependencies to any other groups or items. My question is, has anyone gotten the Zabbix IT Services to work correctly? Is there a trick to getting it to work, some configuration we are doing incorrectly? Thanks, Graham

ISP billing - data collection, correlation, and billing
by Sean Pedersen 17 Jul '17

17 Jul '17

I went back a few years in the archives and found a few odd references, but not much discussion. I'm curious what some other approaches are to usage-based billing, both the practice of generating/correlating data and the billing itself. We bill based on use/95th percentile and our system is rudimentary on its best day. We use SNMP and interface descriptions to generate data and correlate it with customers. This works for the most part, but leaves a lot to be desired. Ours is one method, and I've seen others who use NetFlow data in a similar fashion, with the assumption that the NetFlow data is correlated either via IP address or source interface. Most of the systems I've seen are full-fledged CRM, billing, and OSS, which is a little overkill for us at the moment. I think we would have issues trying to integrate such a multi-headed beast into our organization at this time. What methods do you use to collect and correlate data? What systems, if any, do you use? I'm a little in the dark as the billing/OSS side of things is outside of my normal scope and would appreciate any recommendations. Thanks!

Friday musing - Long distance fiber deployment resources
by nanog-isp＠mail.com 17 Jul '17

17 Jul '17

There are a lot more cows than people with money in rural/remote areas. Getting fiber to remote unserved areas is not a technical problem, it's a money/political problem. On a good day, deploying 400 km of fiber costs in the ballpark of $10M. To that you then have to add the recurring costs of operations, maintenance and fees for the use of the right of way. If the community can pay for that, all is good and well, just have at it. If not, somebody has to subsidize it and then it becomes a political problem. Jared ________________________________ From: NANOG <nanog-bounces at nanog.org> on behalf of Alain Hebert <ahebert at pubnix.net> Sent: Friday, July 14, 2017 8:05 PM To: nanog at nanog.org Subject: Friday musing - Long distance fiber deployment resources Warning: For just plain curiosity at the moment. I was looking for publicly accessible feasibility studies, white papers, etc, about long distance fiber deployment. (> 400km, aka >250 miles) The interest comes from documenting myself about how poorly deserved are the northern communities in Canada. And how "freakn a shame it is to get pwned" by France telecom wise =D. At this point my Goolge Fu is hardly getting thru the pointless clutter search engines accumulated over the years... From the numerous input so far: A lot of the attempts where made to use facilities like rail or electrical grid distribution, but it always ended squashed by a massive push back from the telecom industries, and in one case, maybe the FMI. I'm thinking: If people can invest millions into DOTCOM that put fitbits on cows... There must be a way to help those communities. And ourself, from under the telecom giants.

Reporting/fixing broken airport/hotel/etc wifi?
by Christopher Morrow 15 Jul '17

15 Jul '17

Was there a list of folks collecting to provide fix actions for hotel/airport/etc? Seems that IAD / Washington Dulles don't like "random" tcp/443 sites on the internet? 173.194.205.129 for instance, ping, traceroute, http but no https :( https works just fine from lots of other places on the tubes... just not the dulles wifi. -chris

Anyone have experience with Gripple's seismic bracing vs Unistrut's? Looking at putting something in on the Farallons for a rack there and Gripple's system looks lighter and possibly easier to install... http://grippleseismic.com/wp-content/uploads/downloads/2017/03/BROC-SEISMIC… You can reply directly back to me as I don't know if the rest of the list wants to see this thread.

Testing methodology for the Chinese quantum satellite link?
by Bill Woodcock 14 Jul '17

14 Jul '17

Does anyone who understands quantum networking better than I do have an opinion on the testing methodology that the Chinese team used to confirm entanglement? I guess, more specifically, my question is: when they say that they got 911 positive results out of “millions” of attempts, does this significantly exceed any expected false-positive rate for the confirmation methodology? If so, by what margin? Obviously, if you were just flipping coins, and measured the results once, you’d get 50% positive correlation, twice and you’d get 25% correlation, ten times and you’d get 0.1% correlation, and you’d be at 911 out of a million. So, how much better than that are we talking about? -Bill
