## Deploy multiple bridge monitor on the same host
|
||
|
|
|
||
|
|
If you want to deploy a monitor for different bridges, the [monitor variables](../monitor/.env.example) should be configured in `group_vars/<bridge_name>.yml` for each bridge.
|
||
|
|
|
||
|
|
For example, let's say we are going to deploy a monitor for xDai bridge and for WETC bridge.
|
||
|
|
|
||
|
|
#### Setup ansible configuration for xDai Bridge
|
||
|
|
|
||
|
|
First we create `hosts.yml` file to deploy the monitor for xdai bridge
|
||
|
|
```yaml
|
||
|
|
---
|
||
|
|
xdai:
|
||
|
|
children:
|
||
|
|
monitor:
|
||
|
|
hosts:
|
||
|
|
<host_ip_A>:
|
||
|
|
ansible_user: ubuntu
|
||
|
|
```
|
||
|
|
In `group_vars/xdai.yml`
|
||
|
|
```
|
||
|
|
---
|
||
|
|
MONITOR_BRIDGE_NAME: "xdai"
|
||
|
|
MONITOR_PORT: 3003
|
||
|
|
|
||
|
|
COMMON_HOME_RPC_URL: "https://dai.poa.network"
|
||
|
|
COMMON_HOME_BRIDGE_ADDRESS: "0x7301CFA0e1756B71869E93d4e4Dca5c7d0eb0AA6"
|
||
|
|
COMMON_FOREIGN_RPC_URL: "https://mainnet.infura.io/v3/INFURA_KEY"
|
||
|
|
COMMON_FOREIGN_BRIDGE_ADDRESS: "0x4aa42145Aa6Ebf72e164C9bBC74fbD3788045016"
|
||
|
|
|
||
|
|
COMMON_HOME_GAS_PRICE_FALLBACK: 0
|
||
|
|
COMMON_FOREIGN_GAS_PRICE_SUPPLIER_URL: "https://gasprice.poa.network/"
|
||
|
|
COMMON_FOREIGN_GAS_PRICE_SPEED_TYPE: "standard"
|
||
|
|
COMMON_FOREIGN_GAS_PRICE_FALLBACK: 10000000000
|
||
|
|
COMMON_FOREIGN_GAS_PRICE_FACTOR: 1
|
||
|
|
|
||
|
|
MONITOR_HOME_START_BLOCK: 759
|
||
|
|
MONITOR_FOREIGN_START_BLOCK: 6478417
|
||
|
|
MONITOR_VALIDATOR_HOME_TX_LIMIT: 0
|
||
|
|
MONITOR_VALIDATOR_FOREIGN_TX_LIMIT: 300000
|
||
|
|
MONITOR_TX_NUMBER_THRESHOLD: 100
|
||
|
|
```
|
||
|
|
|
||
|
|
Run the playbook to deploy the monitor for xdai bridge
|
||
|
|
```
|
||
|
|
ansible-playbook -i hosts.yml site.yml
|
||
|
|
```
|
||
|
|
|
||
|
|
This command will deploy the monitor component and enable statistics for xdai bridge.
|
||
|
|
|
||
|
|
#### Setup ansible configuration for WETC Bridge
|
||
|
|
|
||
|
|
Update `hosts.yml` file to deploy the monitor for WETC Bridge
|
||
|
|
```yaml
|
||
|
|
---
|
||
|
|
wetc:
|
||
|
|
children:
|
||
|
|
monitor:
|
||
|
|
hosts:
|
||
|
|
<host_ip_A>:
|
||
|
|
ansible_user: ubuntu
|
||
|
|
```
|
||
|
|
|
||
|
|
In `group_vars/wetc.yml`
|
||
|
|
```
|
||
|
|

|
||
|
|
MONITOR_BRIDGE_NAME: "wetc"

MONITOR_HOME_START_BLOCK: 7703292

MONITOR_FOREIGN_START_BLOCK: 7412459

MONITOR_VALIDATOR_HOME_TX_LIMIT: 300000
|
||
|
|
MONITOR_VALIDATOR_FOREIGN_TX_LIMIT: 300000
|
||
|
|
MONITOR_TX_NUMBER_THRESHOLD: 100
|
||
|
|
```
|
||
|
|
Given that there is a monitor component deployed in the system, the `MONITOR_PORT` variable is not needed.
|
||
|
|
|
||
|
|
Run the playbook to deploy the monitor for WETC Bridge
|
||
|
|
```
|
||
|
|
ansible-playbook -i hosts.yml site.yml
|
||
|
|
```
|
||
|
|
|
||
|
|
They playbook will detect that the monitor component is already deployed in the system, so it will only generate the configuration needed to enable the WETC Bridge statistics.
|
||
|
|
|
||
|
|
##### Get Monitor results
|
||
|
|
The monitor output will be available at `http://host_ip_A:MONITOR_PORT/MONITOR_BRIDGE_NAME`.
|
||
|
|
|
||
|
|
Given that in `xdai.env` the variable `MONITOR_BRIDGE_NAME` is set to `xdai`, the results are in the url `http://host_ip_A:3003/xdai/`.
|
||
|
|
|
||
|
|
Similar to the xdai case, in `wetc.env` the variable `MONITOR_BRIDGE_NAME` is set to `wetc`, so the results are in the url `http://host_ip_A:3003/wetc/`.
