savannadb_agent
===============
An original agent of `SavannaDB`, which is able to easily retrieve metrics and statistics for Erlang's apllications.
## Usage
```erlang
sample() ->
%% ----------------------------------------------------------
%% Launch an agent
%% ----------------------------------------------------------
ok = savanna_agent:start(ram_copies),
ok = savanna_agent:sync_schemas(['[email protected]',
'[email protected]']),
%% ----------------------------------------------------------
%% Create a schema, columns and a metric-group
%% ----------------------------------------------------------
Schema = 'sample',
MetricGroup = 'bucket',
Window = 30,
Col_1 = 'counter_get',
Col_2 = 'length_get',
%% Create schema and columns
ok = svc_tbl_schema:insert(#sv_schema{name = SchemaName,
created_at = leo_date:now()}),
ok = svc_tbl_column:insert(#?SV_COLUMN{id = {SchemaName, Col_1},
schema_name = SchemaName,
name = Col_1,
type = ?COL_TYPE_COUNTER,
created_at = leo_date:now()}),
ok = svc_tbl_column:insert(#?SV_COLUMN{id = {SchemaName, Col_2},
schema_name = SchemaName,
name = Col_2,
type = ?COL_TYPE_H_UNIFORM,
constraint = [{?HISTOGRAM_CONS_SAMPLE, 3000}],
created_at = leo_date:now()}),
%% Create a metric-group
ok = savanna_agent:create_metrics(Schema, MetricGroup, Window),
%% ----------------------------------------------------------
%% Notify events
%% ----------------------------------------------------------
ok = savanna_agent:notify(MetricGroup, Col_1, 1),
ok = savanna_agent:notify(MetricGroup, Col_2, 16384),
ok = savanna_agent:notify(MetricGroup, Col_2, 262144),
ok = savanna_agent:notify(MetricGroup, Col_2, 524288),
ok.
