- Accept Teams as a searchable target type for the target selection API.
- Accept Teams for targets in running live queries.
- Refactoring to support these changes.
- Update API documentation.
Some datastore and service methods would return slices of structs,
rather than slices to pointers of structs (which most methods used).
Make this more consistent.
- Include only hosts that the user has access to in search targets API.
- Add parameter to specify whether `observer` hosts should be included.
- Generate counts based on which hosts user can access.
- Update API doc.
1. use [staticcheck](https://staticcheck.io/) to check the code, and fix some issues.
2. use `go fmt` to format the code.
3. use `go mod tidy` clean the go mod.
- Debounce frontend to reduce number of target searches in live query.
- More efficiently calculate label counts in live query and hosts
dashboard. Instead of using the (slow) CountHostsInTargets function,
retrieve the host counts while looking up the labels.
- Optimize targets search query. Removing the nested query retrieves the
same logical result set, but substantially optimizes MySQL CPU usage.
Testing indicates about a 50% reduction in MySQL CPU usage for the
frontend targets search API call after applying this change.
Replaces the existing calculation that uses a global online interval. This method was lacking due to the fact that different hosts may have different checkin intervals set.
The new calculation uses `min(distributed_interval, config_tls_refresh) + 30` as the interval. This is calculated with the stored values for each host.
Closes#1321
Notable refactoring:
- Use stdlib "context" in place of "golang.org/x/net/context"
- Go-kit no longer wraps errors, so we remove the unwrap in transport_error.go
- Use MakeHandler when setting up endpoint tests (fixes test bug caught during
this refactoring)
Closes#1411.
* Initial scaffolding of the host summary endpoint
* inmem datastore implementation of GenerateHostStatusStatistics
* HostSummary docstring
* changing the url of the host summary endpoint
* datastore tests for GenerateHostStatusStatistics
* MySQL datastore implementation of GenerateHostStatusStatistics
* <= and >= to catch exact time edge case
* removing clock interface method
* lowercase error wraps
* removin superfluous whitespace
* use updated_at
* adding a seen_at column to the hosts table
* moving the update of seen_time to the caller
* using db.Get instead of db.Select
