Error codes

Parsing errors

Error code	Message	Description
23100	No permission to call sentry RPC.	A user without administrator privileges ran the command.
23101	Invalid sentry RPC timeout option value. Use a value between 1 and 600.	The `timeout` option value is not an integer or is outside the range 1–600.

Runtime errors

Errors are returned via the _error field:

Error message	Description
guid is null	The `guid` field value in the input record is null.
guid should be string	The `guid` field value in the input record is not a string.
guid should be non empty string	The `guid` field value in the input record is an empty string.
not connected	The sentry is not connected.
timeout	The RPC request timed out.
disconnected	The connection was lost while processing the RPC request.

Other RPC exception messages may be returned depending on the state of the system where the sentry is installed.

Description

The sentry-routing-table command reads the guid field of each input record, sends an asynchronous RPC message to the corresponding sentry, and retrieves the routing table. The destination, mask, and forward fields are returned as the ipaddr type.

Results are returned in the order RPC response messages are received from sentries, so the output record order may differ from the input record order.

The maximum length of the asynchronous RPC request queue is 100 by default and can be adjusted using the logpresso.core.sentry_rpc_parallel environment variable.

To retrieve results from all Data Nodes at once in a cluster environment, use the sonar-sentry-routing-table command.

Examples

Retrieve the routing table from all sentries
```
sentry | fields guid | sentry-routing-table
```
Retrieves the current routing table from all connected sentries.
Retrieve with a 60-second timeout
```
sentry | fields guid | sentry-routing-table timeout=60
```
Retrieves the routing table from sentries with the RPC timeout set to 60 seconds.
