Functions ¶
func Collect ¶
func Collect(o CollectConfig, dbnames []string) *pgmetrics.Model
Collect actually performs the metrics collection, based on the given options. If database names are specified, it connects to each in turn and accumulates results. If none are specified, the connection is attempted without a 'dbname' keyword (usually tries to connect to a database with same name as the user).
Ideally, this should return (*pgmetrics.Model, error). But for now, it does a log.Fatal(). This will be rectified in the future, and backwards-compatibility will be broken when that happens. You've been warned.
Types ¶
type CollectConfig ¶
type CollectConfig struct {
// general
TimeoutSec uint
NoSizes bool
// collection
Schema string
ExclSchema string
Table string
ExclTable string
SQLLength uint
StmtsLimit uint
Omit []string
// connection
Host string
Port uint16
User string
Password string
}
CollectConfig is a bunch of options passed to the Collect() function to specify which metrics to collect and how.
func DefaultCollectConfig ¶
func DefaultCollectConfig() CollectConfig
DefaultCollectConfig returns a CollectConfig initialized with default values. Some environment variables are consulted.
