Measures reported by CtxGwHATest
A high availability (HA) deployment of two Citrix Cloud Gateway Connectors can provide uninterrupted operation in any transaction. With one connector configured as the primary node and the other as the secondary node, the primary node accepts connections and manages servers while the secondary node monitors the primary. If, for any reason, the primary node is unable to accept connections, the secondary node takes over.
The secondary node monitors the primary by sending periodic messages (often called heartbeat messages or health checks) to determine whether the primary node is accepting connections. If a health check fails, the secondary node retries the connection for a specified period, after which it determines that the primary node is not functioning normally. The secondary node then takes over for the primary (a process called failover).
When monitoring a Citrix Cloud Gateway Connector, you may first want to know whether the target connector has been deployed in an HA setup or not. If so, you may then want to time and again evaluate the effectiveness of the HA configuration, by checking the following:
What is the current status of highly available node in the HA setup? What is the current status of target connector in the HA setup? Has the status of target connector changed?
This is exactly what the CtxGwHATest does.
Outputs of the test :One set of results for the Citrix Cloud Connector Gateway to be monitored.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| HA_state |
Indicates the current state of the highly available node. |
|
The values reported by this measure and its numeric equivalents are mentioned in the table below:
| Measure Value |
Numeric Value |
| Up |
0 |
| Init |
1 |
| Disabled |
2 |
| Partially failed |
3 |
| Completely failed |
4 |
| Dumb |
5 |
| Partially SSL card failed |
6 |
| Route monitor failed |
7 |
Note:
By default, this measure reports the above-mentioned Measure Values while indicating the current state of the highly available node. However, in the graph of this measure, the state will be represented using the corresponding numeric equivalents only. |
| HA_master_state |
Indicates the current state of the master connector in a high availability setup. |
|
The values reported by this measure and its numeric equivalents are mentioned in the table below:
| Measure Value |
Numeric Value |
| Primary |
0 |
| Secondary |
1 |
| Stay Secondary |
2 |
| Claiming |
3 |
| Force change |
4 |
Note:
By default, this measure reports the above-mentioned Measure Values while indicating the current status of the master node. However, in the graph of this measure, the states will be represented using the corresponding numeric equivalents only. |
| Is_master_changed |
Indicates whether/not the state of the target connector changed since the last measurement period. |
|
The values reported by this measure and its numeric equivalents are mentioned in the table below:
| Measure Value |
Numeric Value |
| No |
0 |
| Yes |
1 |
Note:
By default, this measure reports the above-mentioned Measure Values while indicating whether/not the state of the master is changed. However, in the graph of this measure, the states will be represented using the corresponding numeric equivalents only. |
