How to smoothly update OpenFalcon v0.1 to FalconPlus v0.2?

Add New Database List

cd $GOPATH/src/github.com/open-falcon/falcon-plus/scripts/mysql/db_schema/
mysql -h 127.0.0.1 -u root -p < 5_alarms-db-schema.sql

NOTE:

  1. If you want to know how to compile falcon-plus, please refer to falcon-plus readme ;
  2. Or download the official compiled binary pack

Now let's begin our update.

1. Update Agent

Replace the binary file of Agent in v0.1 with the binary file of Falcon-Plus Agent and make some modifications to the configuration file as follows:

diff --git v0.1/agent/cfg.example.json v0.2/agent/cfg.example.json
--- v0.1
+++ v0.2

         "backdoor": false
     },
     "collector": {
-        "ifacePrefix": ["eth", "em"]
+        "ifacePrefix": ["eth", "em"],
+        "mountPoint": []
+    },
+    "default_tags": {
     },
     "ignore": {
         "cpu.busy": true,

2. Update Transfer

Replace the binary file of Transfer in v0.1 with the binary file of Falcon-Plus Transfer. No need for modifications to the configuration file.

3. Update Graph

Replace the binary file of Graph in v0.1 with the binary file of Falcon-Plus Graph. No need for modifications to the configuration file.

4. Replace Query Module with API Module

  1. Stop Query from running
  2. Unzip API and its configuration file from the pack "tar.gz" required from make pack. Enable API module after checking the configuration file as follows:
{
        "log_level": "debug",
        "db": {
                "faclon_portal": "root:@tcp(127.0.0.1:3306)/falcon_portal?charset=utf8&parseTime=True&loc=Local",
                "graph": "root:@tcp(127.0.0.1:3306)/graph?charset=utf8&parseTime=True&loc=Local",
                "uic": "root:@tcp(127.0.0.1:3306)/uic?charset=utf8&parseTime=True&loc=Local",
                "dashboard": "root:@tcp(127.0.0.1:3306)/dashboard?charset=utf8&parseTime=True&loc=Local",
                "alarms": "root:@tcp(127.0.0.1:3306)/alarms?charset=utf8&parseTime=True&loc=Local",
                "db_bug": true
        },
        "graphs": {
                "cluster": {
                        "graph-00": "127.0.0.1:6070"
                },
                "max_conns": 100,
                "max_idle": 100,
                "conn_timeout": 1000,
                "call_timeout": 5000,
                "numberOfReplicas": 500
        },
        "metric_list_file": "./api/data/metric",
        "web_port": ":8080",
        "access_control": true,
        "salt": "",
        "skip_auth": false,
        "signup_disable": false,
        "default_token": "default-token-used-in-server-side",
        "gen_doc": false,
        "gen_doc_path": "doc/module.html"
}

db part is about the information of database connection. Just change it according to actual usage. graphs part is about the information of Graph list in the backend. Just keep its content the same as the content in cfg.json of Query in v0.1.

5. Update HBS

Replace the binary file of HBS in v0.1 with the binary file of Falcon-Plus HBS. No need for modifications to the configuration file.

6. Update Judge

Replace the binary file of Judge in v0.1 with the binary file of Falcon-Plus Judge. No need for modifications to the configuration file.

7. Update Alarm

Replace the binary file of Alarm in v0.1 with the binary file of Falcon-Plus Alarm and make some modifications to the configuration file as follows:

diff --git v0.1/alarm/cfg.example.json v0.2/alarm/cfg.example.json
--- v0.1/alarm/cfg.example.json

 }

NOTE: Sender module was removed from v0.2 and its feature has been integrated to Alarm module, which lower the cost of user's configuration and maintenance. Sending via WeChat is supported by this version.

8. Update Aggregator

Replace the binary file of Aggregator in v0.1 with the binary file of Falcon-Plus Aggregator and make some modifications to the configuration file as follows:

diff --git v0.1/aggregator/cfg.example.json v0.2/aggregator/cfg.example.json

     }
 }

NOTE: Aggregator directly interacts with the API of Falcon-Plus, which is the address configured by plus_api.

9. Update Nodata

NOTE: Nodata does not visit Query anymore. Instead, it directly communicate with the API of Falcon-Plus, which is plus_api configuration.

10. Update Gateway

Replace the binary file of Gateway in v0.1 with the binary file of Falcon-Plus Gateway. No need for modifications to the configuration file.

11. Enable Brand-New Integrated Frontend Modules
