Fixes issue where `fleetctl get options` returns `option` (singular)
as `kind` instead of `options` (plural). This would cause `fleetctl
apply -f options.yml` to fail on options yaml generated by `fleetctl get
options` with this error: `unknown kind "option"`.
- 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.
Getting a single host with `fleetctl get host foobar` will look up the
host with the matching hostname, uuid, osquery identifier, or node key,
and provide the full host details along with the labels the host is a
member of.
"Manual" labels can be specified by hostname, allowing users to specify
the membership of a label without having to use a dynamic query. See the
included documentation.
Label membership is now stored in the label_membership table. This is
done in preparation for adding "manual" labels, as previously label
membership was associated directly with label query executions.
Label queries are now all executed at the same time, rather than on
separate intervals. This simplifies the calculation of which distributed
queries need to be run when a host checks in.
This commit takes advantage of the existing pagination APIs in the Fleet
server, and provides additional APIs to support pagination in the web
UI. Doing this dramatically reduces the response sizes for requests from
the UI, and limits the performance impact of UI clients on the Fleet and
MySQL servers.
This change optimizes live queries by pushing the computation of query
targets to the creation time of the query, and efficiently caching the
targets in Redis. This results in a huge performance improvement at both
steady-state, and when running live queries.
- Live queries are stored using a bitfield in Redis, and takes
advantage of bitfield operations to be extremely efficient.
- Only run Redis live query test when REDIS_TEST is set in environment
- Ensure that live queries are only sent to hosts when there is a client
listening for results. Addresses an existing issue in Fleet along with
appropriate cleanup for the refactored live query backend.
Fleet used significant resources storing the full network interface
information for each host. This data was unused, except to get the
IP and MAC of the primary interface. With these changes, only those
pieces of data are stored.
- Calculate and store primary IP and MAC
- Remove transaction for storing full interfaces
- Update targets search to use new IP and MAC columns
- Update frontend to use new new columns
This PR removes unused types, code, DB tables, and associated migrations that are unused since Fleet 2.0.
An existing migration was refactored, and should remain compatible with both existing and new Fleet installations.
Additional information is collected when host details are updated using
the queries specified in the Fleet configuration. This additional
information is then available in the host API responses.
This adds a SQL injection prevention for a case in which we cannot use
parameters in the query.
It is not clear that this was possible to exploit. If it was possible,
it would have required a valid login to the Fleet server.
Fleet does not use CGO. In some build situations, not explicitly
disabling CGO results in binaries that have linking errors when running
on an Alpine Docker container. This change should fix the build for
those containers.
Previously a Go package attempting to import Fleet packages would run
into an error like "server/kolide/emails.go:93:23: undefined: Asset".
This commit refactors bindata asset handling to allow importing Fleet as
a library without changing the typical developer experience.
