> Collect and monitor the general performance Metrics of nebulaGraph.
|
||
|
||
**Protocol Use：nebulaGraph**
|
||
|
||
```text
|
||
The monitoring has two parts,nebulaGraph_stats and rocksdb_stats.
|
||
nebulaGraph_stats is nebulaGraph's statistics, and rocksdb_stats is rocksdb's statistics.
|
||
```
|
||
|
||
**1、Obtain available parameters through the stats and rocksdb stats interfaces.**
|
||
|
||
1.1、 If you only need to get nebulaGraph_stats, you need to ensure that you have access to stats, or you'll get errors.
|
||
|
||
The default port is 19669 and the access address is [http://ip:19669/stats](http://ip:19669/stats)
|
||
|
||
1.2、If you need to obtain additional parameters for rocksdb stats, you need to ensure that you have access to rocksdb
|
||
stats, otherwise an error will be reported.
|
||
|
||
Once you connect to NebulaGraph for the first time, you must first register your Storage service in order to properly
|
||
query your data.
