|
||||
|
||||
## `info()` (experimental)
|
||||
|
||||
_The `info` function is an experiment to improve UX
|
||||
around including labels from [info metrics](https://grafana.com/blog/2021/08/04/how-to-use-promql-joins-for-more-effective-queries-of-prometheus-metrics-at-scale/#info-metrics).
|
||||
The behavior of this function may change in future versions of Prometheus,
|
||||
including its removal from PromQL. `info` has to be enabled via the
|
||||
[feature flag](../feature_flags.md#experimental-promql-functions) `--enable-feature=promql-experimental-functions`._
|
||||
|
||||
`info(v instant-vector, [data-label-selector instant-vector])` finds, for each time
|
||||
series in `v`, all info series with matching _identifying_ labels (more on
|
||||
this later), and adds the union of their _data_ (i.e., non-identifying) labels
|
||||
to the time series. The second argument `data-label-selector` is optional.
|
||||
It is not a real instant vector, but uses a subset of its syntax.
|
||||
It must start and end with curly braces (`{ ... }`) and may only contain label matchers.
|
||||
The label matchers are used to constrain which info series to consider
|
||||
and which data labels to add to `v`.
|
||||
|
||||
Identifying labels of an info series are the subset of labels that uniquely
|
||||
identify the info series. The remaining labels are considered
|
||||
_data labels_ (also called non-identifying). (Note that Prometheus's concept
|
||||
of time series identity always includes _all_ the labels. For the sake of the `info`
|
||||
function, we “logically” define info series identity in a different way than
|
||||
in the conventional Prometheus view.) The identifying labels of an info series
|
||||
are used to join it to regular (non-info) series, i.e. those series that have
|
||||
the same labels as the identifying labels of the info series. The data labels, which are
|
||||
the ones added to the regular series by the `info` function, effectively encode
|
||||
metadata key value pairs. (This implies that a change in the data labels
|
||||
in the conventional Prometheus view constitutes the end of one info series and
|
||||
the beginning of a new info series, while the “logical” view of the `info` function is
|
||||
that the same info series continues to exist, just with different “data”.)
|
||||
|
||||
The conventional approach of adding data labels is sometimes called a “join query”,
|
||||
as illustrated by the following example:
|
||||
|
||||
```
|
||||
rate(http_server_request_duration_seconds_count[2m])
|
||||
* on (job, instance) group_left (k8s_cluster_name)
|
||||
target_info
|
||||
```
|
||||
|
||||
The core of the query is the expression `rate(http_server_request_duration_seconds_count[2m])`.
|
||||
But to add data labels from an info metric, the user has to use elaborate
|
||||
(and not very obvious) syntax to specify which info metric to use (`target_info`), what the
|
||||
identifying labels are (`on (job, instance)`), and which data labels to add
|
||||
(`group_left (k8s_cluster_name)`).
|
||||
|
||||
This query is not only verbose and hard to write, it might also run into an “identity crisis”:
|
||||
If any of the data labels of `target_info` changes, Prometheus sees that as a change of series
|
||||
(as alluded to above, Prometheus just has no native concept of non-identifying labels).
|
||||
If the old `target_info` series is not properly marked as stale (which can happen with certain ingestion paths),
|
||||
the query above will fail for up to 5m (the lookback delta) because it will find a conflicting
|
||||
match with both the old and the new version of `target_info`.
|
||||
|
||||
The `info` function not only resolves this conflict in favor of the newer series, it also simplifies the syntax
|
||||
because it knows about the available info series and what their identifying labels are. The example query
|
||||
looks like this with the `info` function:
|
||||
|
||||
```
|
||||
info(
|
||||
rate(http_server_request_duration_seconds_count[2m]),
|
||||
{k8s_cluster_name=~".+"}
|
||||
)
|
||||
```
|
||||
|
||||
The common case of adding _all_ data labels can be achieved by
|
||||
omitting the 2nd argument of the `info` function entirely, simplifying
|
||||
the example even more:
|
||||
|
||||
```
|
||||
info(rate(http_server_request_duration_seconds_count[2m]))
|
||||
```
|
||||
|
||||
While `info` normally automatically finds all matching info series, it's possible to
|
||||
restrict them by providing a `__name__` label matcher, e.g.
|
||||
`{__name__="target_info"}`.
|
||||
|
||||
### Limitations
|
||||
|
||||
In its current iteration, `info` defaults to considering only info series with
|
||||
the name `target_info`. It also assumes that the identifying info series labels are
|
||||
`instance` and `job`. `info` does support other info series names however, through
|
||||
`__name__` label matchers. E.g., one can explicitly say to consider both
|
||||
`target_info` and `build_info` as follows:
|
||||
`{__name__=~"(target|build)_info"}`. However, the identifying labels always
|
||||
have to be `instance` and `job`.
|
||||
|
||||
These limitations are partially defeating the purpose of the `info` function.
|
||||
At the current stage, this is an experiment to find out how useful the approach
|
||||
turns out to be in practice. A final version of the `info` function will indeed
|
||||
consider all matching info series and with their appropriate identifying labels.
