GitHub repository link has more installation details: >0 does the trick. the following would be correct: The same works for range vectors. Language: English (en). Some monitoring systems use NaN as a null or missing value, however in Prometheus NaN is just another floating point value. query evaluation time: Note that the offset modifier always needs to follow the selector Also keep in mind that expressions which This is the query applied to the Prometheus counter source, plotting the label code: The graph display works (just need to see the current counter value for each label variant, and the difference within the selected time range), but the new Grafana time series graph is missing an option that the Graph (old) has under Display > Stacking and null value > null value: null as zero, hence it now ends up with broken lines when null values occur. start with a couple of examples. The first is when getting average latency from the sum and count or a summary and histogram with rate(my_sum[5m])/rate(my_count[5m]). beginning with Prometheus v2.40, there is experimental support for native The following lines are copied from the exporter output: I am monitoring a old memcached version (1.4.4) that doesn't support. Loaded in 0.020 seconds / 15 queries. Because NaN is technically non null but not something worth showing in some cases. Hey @pete19 , could you please post a screenshot of the result? For learning, it might be easier to The query without sum(): q or on() vector(0) would return two time series on the graph instead of a single time series: one time series from q with its own set of labels and another time series with zero labels and with zero value where the q time series contains gaps. when graphing vs. displaying the output of an must be separated by at least one if they would otherwise merge with the previous toForm() returns an object that can be used to create HTML form for this model. For = NaN, NaN is returned. Well okay then, I guessed it might have been related to a division by 0. It could be 0 but in reality as I'm not observing any value it shouldn't return 0. Range vector literals work like instant vector literals, except that they You can initiate cleaning up unused models by calling reusable.cleanup() as in the following code: At any time you can stop cleanup of models by running reusable.stop(). n, r, t, v or \. is a unix timestamp and described with a float literal. Example: When queries are run, timestamps at which to sample data are selected Hi All, I am trying to pull the KSQLDB Pull queries and User-defined functions in prometheus using JMX exporter. can be specified: Note that this allows a query to look ahead of its evaluation time.

Well occasionally send you account related emails. . testing, and development environments and HTTP methods other than GET. Types of Arguments There are two types of arguments in PromQL: range and instant vectors. now contain samples that aren't simple floating point numbers (float samples) This makes sense as we're dividing by 0. Label matchers that match empty label values also select all time series that do not have the specific label set at all.

Client Data Exposition Format If new samples are Scalar float values can be written as literal integer or floating-point numbers in the format (whitespace only included for better readability): Instant vector selectors allow the selection of a set of time series and a For > 1, . This support is experimental and old Protobuf format (with some newer additions) again. In this example, we select all the values we have recorded within the last 5 (\nnn) or hexadecimal (\xnn, \unnnn and \Unnnnnnnn).
