Grafana diffseries


Learn about Grafana the monitoring solution for every database. Open Source is at the heart of what we do at Grafana Labs. It reduces the series into a single number by looking at the max, min, average, or sum of values in the series. Singlestat also provides thresholds to color the stat or the Panel background.

It can also translate the single number into a text value, and show a sparkline summary of the series. The singlestat panel has a normal query editor to allow you define your exact metric queries like many other Panels. In the Options tab, you can access the Singlestat-specific functionality. The coloring options of the Singlestat Panel config allow you to dynamically change the colors based on the Singlestat value.

Sparklines are a great way of seeing the historical data related to the summary stat, providing valuable context at a glance. Sparklines act differently than traditional Graph Panels and do not include x or y axis, coordinates, a legend, or ability to interact with the graph.

The text will respect all styling, thresholds and customization defined for the value.

This can be useful to translate the number of the main Singlestat value into a context-specific human-readable word or message. Grafana 2. In previous versions, the panel logic did not verify that only a single series was used, and instead, displayed the first series encountered.

It is a very simple a few hundred lines of code NodeJS daemon that listens on a UDP port, extracts metric data from the messages and flushes them from time to time to Graphite.

Graphite is both a numeric time-series data storage and a graphical frontend rendering of this data. It includes 3 components:. Grafana is a rich graphical frontend that allows you to display data from multiple sources like Graphite, InfluxDB, Elasticsearch, and more.

A few months back, a customer showed me what they had accomplished with Grafana, and I thought it looks very good. This time I decided to go the Docker route. The installation will create a small Linux VM to serve as the host for your containers. If you run on Linux, use your host name or IP address. As it was my only container, those ports were available; you may need to redirect them.

Check the Docker documentation for details. In our case, this is the IP of the VM hosting the containers. You may need to use the port on your Docker machine that you forward to in the statsd container. In order for any modification in this file to take effect, you need to restart your ElectricFlow server daemon. However, a data point must have been generated before you see it automatically. This is not an exhaustive list, but some key metrics to keep in mind, and data that we also monitor internally.

Now that you have a statsd server running with a graphing frontend, why not take advantage of it to send some run-time data? You can simply send those 2 data points to statsd with the following code:.

This means that when something fails on an API, I only get a graph on that a request has failed, but not relative to traffic.

I'm trying to subtract the sum of a couple graphite metrics from the sum of a couple of other graphite metrics over a summarized period of time. However, I'm getting different results depending on whether I summarize before or after I do diffSeries. With summarize on the outside of diffSeries as above I get numbers that seem way too high based on looking at the raw data in csv exports. The above seems to give me the right data, but I'd rather only have to summarize once and can't for the life of me figure out why it should be different.

It seems like the arguments to diffSeries are getting messed up when I just pass them in as sums and don't summarize too, but I'm not sure how. I'm not entirely sure, but was also getting some strange behaviour with diffSeries.

In my case it looked like I was always getting positive diffs, when it should have been negative. Looking at the code, diffSeries uses a function called safeDiff. It looks to me like the first line of the function might be the culprit.

It only takes values that are not Noneso if you try to diff a numeric value from Noneit will output the positive numeric value Where I would have expected a negative one. I couldn't find a function in graphite to do so. Learn more. Order of summarize and diffSeries with graphite Ask Question. Asked 7 years, 4 months ago.

Unfortunately Bucky feeds the raw metrics like. But what we need are metrics that are already computed and more meaningful, like "Total Page Load Time" and etc. To address this I was thinking of computing these values myself, however Grafana's metric input for OpenTSDB don't seem to have operations like that like for its support for Graphite which has diffSeries to do subtraction.

Stack Overflow works best with JavaScript enabled.Functions are used to transform, combine, and perform computations on series data. Functions are applied using the Composer interface or by manipulating the target parameters in the Render API. Most functions are applied to one series list. To pass multiple series lists to a function which only takes one, use the group function. Takes one metric or a wildcard seriesList and applies the mathematical abs function to each datapoint transforming it to its absolute value.

Takes one metric or a wildcard seriesList followed by a constant, and adds the constant to each datapoint. Also works for negative numbers. Takes a metric or wildcard seriesList and draws a horizontal line based on the function applied to each series. If the optional keepStep parameter is set to True, the result will have the same time period and step as the source series. Note: By default, the graphite renderer consolidates data points by averaging data points over time.

To fix this, you should use the consolidateBy function with the same function argument you are using for aggregateLine. This will ensure that the proper data points are retained and the graph should line up correctly. This complements groupByNodes which takes a list of nodes that must match in each group. Takes one metric or a wildcard seriesList and a string in quotes. Prints the string instead of the metric name in the legend. Node indices are 0 indexed.

This is an alias for aliasByNode. Takes a seriesList and applies some complicated function described by a stringreplacing templates with unique prefixes of keys from the seriesList the key is all nodes up to the index given as nodeNum. Would find all series which match servers. The output series would have keys stats. Draws the vertical area in between the two series in seriesList. Useful for visualizing a range such as the minimum and maximum latency for a service.

The order of the lower and higher values series does not matter. Most likely use case is to provide a band within which another metric should move. In such case applying an alphaas in the second example, gives best visual results. If for instance, you need to build a seriesList, you should use the group function, like so:.

Calculates a percentage of the total of a wildcard series. If total is specified, each series will be calculated as a percentage of that total. If total is not specified, the sum of all points in the wildcard series will be used instead.

A list of nodes can optionally be provided, if so they will be used to match series with their corresponding totals following the same logic as groupByNodes. When passing nodes the total parameter may be a series list or None. If it is None then for each series in seriesList the percentage of the sum of series in that group will be returned. When not passing nodesthe total parameter may be a single series, reference the same number of series as seriesList or be a numeric value.

When total is a seriesList, specifying nodes to match series with the corresponding total series will increase reliability. Takes one metric or a wildcard seriesList followed by a constant N. Out of all metrics passed, draws only the metrics with an average value above N for the time period specified.

Out of all metrics passed, draws only the metrics with an average value below N for the time period specified. Takes one metric or a wildcard seriesList. Draws the average value of all metrics passed at each time.

How can I summarize graphite data depending on the selected interval? If the selected interval is up to 1 hour, the data counter should show data points for every minute.

If the interval is up to 3 hours, the data should be summarized over 5 minutes. If the interval is up to 1 day, the data should be summarized over 15 minutes. However since Graphite has a public API you can script this yourself automatically to retrieve the graph with the correct summarizing period.

Grafana for example does this when using the 'auto' option for interval template. You can get something close this this using by creating an interval template variable, enable the Auto option, and set number of steps. In the example below it's set to 40 steps so it will pick an appropriate interval based on the time range. Use the variable like this:.
