示例1: queryCount
// queryCount returns the total SQL queries executed by the cluster.
func (cl continuousLoadTest) queryCount(f *terrafarm.Farmer) (float64, error) {
var client http.Client
var resp status.NodeStatus
host := f.Hostname(0)
if err := httputil.GetJSON(client, "http://"+host+":8080/_status/nodes/local", &resp); err != nil {
return 0, err
}
count, ok := resp.Metrics["sql.query.count"]
if !ok {
return 0, errors.New("couldn't find SQL query count metric")
}
return count, nil
}示例2: startLoad
func (cl continuousLoadTest) startLoad(f *terrafarm.Farmer) error {
if *flagCLTWriters > len(f.Nodes()) {
return errors.Errorf("writers (%d) > nodes (%d)", *flagCLTWriters, len(f.Nodes()))
}
// We may have to retry restarting the load generators, because CockroachDB
// might have been started too recently to start accepting connections.
started := make(map[int]bool)
return util.RetryForDuration(10*time.Second, func() error {
for i := 0; i < *flagCLTWriters; i++ {
if !started[i] {
if err := f.Start(i, cl.Process); err != nil {
return err
}
}
}
return nil
})
}示例3: assert
// assert fails the test if CockroachDB or the load generators are down.
func (cl continuousLoadTest) assert(t *testing.T, f *terrafarm.Farmer) {
f.Assert(t)
for _, host := range f.Nodes()[0:*flagCLTWriters] {
f.AssertState(t, host, cl.Process, "RUNNING")
}
