I have noticed that the the FreeBSD version of metricbeat has the uptime metricset of the system module disabled (or not enabled) in the Go build tags for the metricset. Consequently, when building metricbeat on FreeBSD, the uptime metricset is not enabled & will throw errors if configured in the metricbeat configuration.
```auto
2018-12-05T00:02:02.391Z ERROR instance/beat.go:824 Exiting: 1 error: 1 error: metricset 'system/uptime' is not registered, metricset not found
```
Here is the go file for the uptime metricset:

import (
"github.com/pkg/errors"
"github.com/elastic/beats/libbeat/common"
"github.com/elastic/beats/metricbeat/mb"
"github.com/elastic/beats/metricbeat/mb/parse"
sigar "github.com/elastic/gosigar"
)
func init() {
mb.Registry.MustAddMetricSet("system", "uptime", New,
mb.WithHostParser(parse.EmptyHostParser),
mb.DefaultMetricSet(),
)
}
// MetricSet for fetching an OS uptime metric.
type MetricSet struct {
mb.BaseMetricSet
}
// New is a mb.MetricSetFactory that returns a new MetricSet.
func New(base mb.BaseMetricSet) (mb.MetricSet, error) {
return &MetricSet{base}, nil
}
// Fetch fetches the uptime metric from the OS.
func (m *MetricSet) Fetch() (common.MapStr, error) {
var uptime sigar.Uptime
if err := uptime.Get(); err != nil {
return nil, errors.Wrap(err, "failed to get uptime")
}
return common.MapStr{
"duration": common.MapStr{
"ms": int64(uptime.Length * 1000),
},
}, nil
}
```
is there any particular reason it's not enabled there? I see in gosigar's freebsd file sigar\_freebsd.go that there is an uptime function using FreeBSD's clock\_gettime sytem call:
```auto
func (self *Uptime) Get() error {
ts := C.struct_timespec{}
if _, err := C.clock_gettime(C.CLOCK_UPTIME, &ts); err != nil {
return err
}
self.Length = float64(ts.tv_sec) + 1e-9*float64(ts.tv_nsec)
return nil
}
```
I have enabled the build flag, built metricbeat on FreeBSD 11.2, run metricbeat, & get correct uptime events issued to logstash & stored in Elasticsearch.
```json

```
Is this an oversight, or is there a deeper reason it's not enabled for FreeBSD?

Hello! I think by default, besides system module, everything else is disabled.

I am referring to the uptime metricset, which is part of the system module. In the code, it's enabled for darwin linux openbsd, & windows, but not FreeBSD. I'm wondering why, since it appears to work fine, on FreeBSD 11 at any rate. If there isn't some underlying reason not to enable this for FreeBSD, then I believe this should be considered a bug.

@rhclayto thanks for the explanation 🙂 I'm glad it works! I will create a github issue to make it be enabled by default.

Thanks. Do you have a link to the Github issue? I'd like to follow it there. Or I can create an issue if you haven't already done so.
Edit:
Nevermind, found it: [https://github.com/elastic/beats/pull/9413](https://github.com/elastic/beats/pull/9413)
