Hi,
My data center bills me based on 95th percentile and Mbps, but Observium shows traffic as bits/second.
My monthly allowance is 100Mbps, how would I convert that to the bits/second in 95th? They also state they bill me on bandwidth utilization, not data used.
Finally, they state they use 5 minute intervals for data collection, I guess that's also called 'polling' if I'm not mistaken? I could not find any info on how often the data is collected.
Just to clarify, if I got the calculation right - 100Mbps = 30TB /mo (rounded off).
Are you using CE or Pro?
With Pro the best thing would be to create a bill which matches the ports that your provider is billing, that way you'll be basically collecting the same data that your provider is.
With CE, you can look at the '95th' line on traffic graphs. The red line is approximated 95th, but it's not accurate since we don't store 5-minute data for a full month.

Hi,
I’m using CE.
Basically what I did was run the traffic graph for my main router to the facility’s upstream (uplink basically). I did the entire month of June to the exact second.
I just did a quick “last month” output
Total
In 60TB
Out 60TB
Agg 120
How would I convert this to Mbps in 95th? Sorry, still learning this calculation.
How often does the CE version poll data anyway and can it be changed?
Phillp Baker stated that it shows Mbps as “M”, so if I figured this out right, the above AS IS is 200MBps. But, is Observium CE stating this in 95th or do I have to figure this out manually what 95th it will be?
Please note what I quoted before “They also state they bill me on bandwidth utilization, not data used.” Anyone know what they might mean by this? I haven’t asked them yet, been going back and forth but slow responses.

I don’t understand. Don’t you have a legend that looks like the attached on every graph?
You can see the 95th figures there.
Observium is designed on 5 minute like everyone else, pretty much. You can probably change it but you really don’t need to (and it isn’t as easy as changing the cron job frequency)

Yes, but only when viewing specific ports, not the router itself.
I just checked for the specific port to the uplink, my mistake.
I just ran for the full month of June. Please see attached.
They told me the following
“bandwidth utilization data captured both inbound and outbound usage. They are both used in calculating 95% values, but they are not added together or combined.
If the customer’s 95% is 90Mbps for inbound, and 26Mbps for outbound, they are only billed using the 90Mbps value. (not 90+26)”
So based on the graph, I would have been billed for the 176MBps (converted as 52.8TB). Correct? Just making sure I’m understanding the calculations.
And according to what you’re saying, it polls every 5 minutes which is what the data center does too. So my graph should be generally very accurate.

You’ll be billed for ~194.63mbps as that is the larger of the two, if that is the port facing your supplier that they bill you for.
The 95th does not “convert” into a usage figure, because it is not the mean usage figure you would use to estimate bytes transferred.
Forget thinking in terms of bytes per month (I don’t know why you’re asking about bytes per month, really?), because it’s a relatively meaningless metric if your datacentre is billing you in mbps 95th percentile unless you are considering changing to a supplier that will bill you in bytes per month. It is entirely possible to generate a
You can see on that graph that while the outbound 95th was 194mbps your actual outbound data transferred over that period was only ~43.17, whereas if you had used 194.63mbps *consistently* over the month (eg: your average was then also 194.63mbps), your transferred bytes would be in the region of 58TB.
Assuming your port was fast enough, you could blow through your 60TB in 36 hours (and do NOTHING for the rest of the month) and you’d a bill for ~3700mbps of usage on 95th percentile. This is why bytes transferred per month is not a useful metric when you’re trying to figure out 95th percentiles. Bytes per month can only be converted to an average of bits per second, not to the 95th. I don’t know if I can explain this any other way.
The data in the RRD will not be of billing-accuracy and you will likely see a discrepancy between your 95th and the provider’s 95th. You need a pro subscription and a traffic accounting bill to get the correct granularity for accurate 95th calculation.

Hi,
Its normal to be billed on the largest of the in/out 95th values, so you'd probably be billed on the larger one.
It is definitely time for you to upgrade your commitment to 200mbps to avoid overage charges next billing cycle.
I would recommend perhaps purchasing a pro subscription so that you can use our billing system to generate estimations ahead of time so you can keep track of things in future.

Basically what I did was run the traffic graph for my main router to the facility’s upstream (uplink basically). I did the entire month of June to the exact second.
I just did a quick “last month” output
Total
In 60TB
Out 60TB
Agg 120
How would I convert this to Mbps in 95th? Sorry, still learning this calculation.
How often does the CE version poll data anyway and can it be changed?
Phillp Baker stated that it shows Mbps as “M”, so if I figured this out right, the above AS IS is 200MBps. But, is Observium CE stating this in 95th or do I have to figure this out manually what 95th it will be?
Please note what I quoted before “They also state they bill me on bandwidth utilization, not data used.” Anyone know what they might mean by this? I haven’t asked them yet, been going back and forth but slow responses.

Are you using CE or Pro?
With Pro the best thing would be to create a bill which matches the ports that your provider is billing, that way you'll be basically collecting the same data that your provider is.
With CE, you can look at the '95th' line on traffic graphs. The red line is approximated 95th, but it's not accurate since we don't store 5-minute data for a full month.

Hi,
My data center bills me based on 95th percentile and Mbps, but Observium shows traffic as bits/second.
My monthly allowance is 100Mbps, how would I convert that to the bits/second in 95th? They also state they bill me on bandwidth utilization, not data used.
Finally, they state they use 5 minute intervals for data collection, I guess that’s also called ‘polling’ if I’m not mistaken? I could not find any info on how often the data is collected.
Just to clarify, if I got the calculation right – 100Mbps = 30TB /mo (rounded off).

Thanks Adam.
It is 200Mbps, I wrongly stated 100Mbps before. Long day.
So 200Mbps = 60TB monthly usage (rounded off the 59.x).
That means based off the graph for June, I used 176.xMBps (52.8TB). They’re billing 9Mbps over the 200Mbps usage, hence my concern.

Hi,
Its normal to be billed on the largest of the in/out 95th values, so you'd probably be billed on the larger one.
It is definitely time for you to upgrade your commitment to 200mbps to avoid overage charges next billing cycle.
I would recommend perhaps purchasing a pro subscription so that you can use our billing system to generate estimations ahead of time so you can keep track of things in future.

Yes, but only when viewing specific ports, not the router itself.
I just checked for the specific port to the uplink, my mistake.
I just ran for the full month of June. Please see attached.
They told me the following
“bandwidth utilization data captured both inbound and outbound usage. They are both used in calculating 95% values, but they are not added together or combined.
If the customer’s 95% is 90Mbps for inbound, and 26Mbps for outbound, they are only billed using the 90Mbps value. (not 90+26)”
So based on the graph, I would have been billed for the 176MBps (converted as 52.8TB). Correct? Just making sure I’m understanding the calculations.
And according to what you’re saying, it polls every 5 minutes which is what the data center does too. So my graph should be generally very accurate.

95th percentile billing doesn't have a direct relationship to GB transferred.
It is possible to use 0bps for 29 days, but get charged for 1gbps because you did 1gbps for 37 hours.
Imagine you have 100 data points. Arrange them by size. The 95th point (the 5tg largest) is the amount you are billed on. This is 95th %ile.
RRDtools graphs are somewhat lossy (the technical details of rrd are quite complex, but suffice to say that we only store 5 minute samples for a few days, after that 30 minute samples for a few weeks then 2 hour samples for a couple of years (or there about)). This is done to allow rrdtool to scale.
Its possible that rrds averaging has lowered the 95th it reports to you (this is why the mysql-based billing system exists, since rrd isn't reliable for this), and your provider's bill is accurate.
Note that even if you have 5 minute samples for the entire period, there are often differences since the samples won't have been taken at exactly the same time!
Billing. Blegh!

An individual port bits graph has a 95th column in the legend.
Observium polls every 5 minutes. Its theoretically changeable, but requires the deletion of all historical data, so is a bad idea :)

observium mailing list observium@observium.org http://postman.memetic.org/cgi-bin/mailman/listinfo/observium
Mbps is megabits per second. You need one million bits per second per megabit per second, but... observium graphs will show you mbps (as "M") as soon as you're doing enough traffic for it to be counted in mbps instead of bits, because they scale automatically, no?
CE won't show you billing-accuracy 95th data for monthly graphs, but it'll be vaguely right most of the time. If you have pro, set up a bill under traffic accounting to get accurate data.
30TB if you use it evenly will be under 100mbps, yes, but if you spend more than ~36 hours a month doing more than 100mbps, you'll get billed for more usage.
