RE: RTG
Hi Nick, At the time MRTG was the thing that everyone was using and the way it handled numbers and how it stored those numbers made it challenging to use for our use case. The things that we like about RTG are that it collects raw (non-smoothed) numbers (usage) and it stores those numbers in a well known RDBMS. This has made it extremely easy to integrate that data in other applications and with other data sources such as sflow/netflow to do some interesting things. It is also very easy to include graphs generated by RTG in other applications. The primary pain point is how it handles 'targets' for polling and the targetmaker script itself. I will check out Libre.

Re: RTG
I too love RTG, been using it forever, appears to handle interfaces all the way up 10G. Out of curiosity, are you hitting an issue that requires updating? I get it, there are many options now, but back in the day, RTG was so simple and so useful, its a testament to the original product. Its a great light weight traffic monitor, at my old datacenter I monitored over 2000 interfaces (with up to 2 years of retention) from a very basic low-end single CPU box. -John > On Oct 30, 2019, at 8:25 AM, Drew Weaver wrote: > > Hello, > > We’ve been using this product for years and years http://rtg.sourceforge.net/ > <http://rtg.sourceforge.net/> to collect and store SNMP statistics. > > It has been working fine for us.

RTG
Hello, We've been using this product for years and years http://rtg.sourceforge.net/ to collect and store SNMP statistics. It has been working fine for us. I haven't really been able to find much information about forks, new versions, and development happening on it. A while back I heard that Yahoo created their own version of it but I could never find it. Does anyone know if there is a spiritual successor to RTG that pretty much works the same way that is modernized? Thanks! -Drew
Re: collectd as alternative to RTG for high-resolution polling and long term storage?
Collectd is great, IMHO. I was using collectd+graphite to gather and display stats for a large collection of VMs, servers, routers, and switches. Collectd itself was pretty low overhead, easy to configure (I managed configs via puppet) and Just Worked. Graphite and carbon cache were a little more tricky to set up - carbon by default aggregates/averages older data, so if not setup correctly, when you go back a few months and try to drill into a graph at a 5 minute interval, you get unexpected results. I’d highly recommend looking at Graphite, as well. Once you get used to it, being able to apply functions[1] to aggregate, manipulate, and quickly find patterns in data is super useful (ex: look at all interfaces on this switch, only display graphs for the top 5 abnormal traffic). Jason Dixon has written some great blogs posts about it’s use on obfuscurity.com.

You might check out Grafana (http://grafana.org/ <http://grafana.org/>). Its based off graphite and uses something like opentsdb or influxdb for the backend.

No, the storage interval is configurable and so are the (optional) consolidation functions. You may want to look tuning at the defaults your application is choosing. Dale

Collectd supports a large number “write” plugins[1] that can write out to various sources.

Host sFlow (http://sflow.net) is very similar to collectd in the metrics it exports, but with the added ability to export flow data from host adapters, bridges, vSwitches, firewalls, routing, VMs, containers etc.
Re: collectd as alternative to RTG for high-resolution polling and long term storage?
Be aware that collectd itself is a collection agent. It doesn't include (last I checked) a grapher. There are however a number of graphers out there to work with those RRD files, if you use that to store the data. I personally have been using collectd across hundreds of Linux systems, using rrdcached to a central collector and wrote my own grapher for that stuff I am interested int. Ulf.

collectd as alternative to RTG for high-resolution polling and long term storage?
Would anyone care to share their experience using collectd as an alternative to rtg for high-resolution polling of interface traffic and long term storage? I am investigating the various options for large data set size, lossless long term traffic charting (not RRAs which lose precision over time). One possible use is precision 95th billing. https://collectd.org/
