Retrieves the stack status information of the thread with highest CPU usage in a sentry. This command is useful when remotely diagnosing CPU load issue of sentry.
- RPC timeout in seconds (default: 30 seconds)
This query command sends asynchronous RPC request messages to 100 sentries at the same time and waits for responses.The RPC request message queue operates on a first-in, first-out (FIFO) basis. For example, if the Logpresso server needs to send RPC messages to 150 sentries, the server sends an RPC message to 100 sentries first and waits until RPC responses. If the waiting time exceeds the time specified in the
timeout (default: 30 seconds), it is considered that an error has occurred on the sentry side. If 32 out of 100 sentries respond or timeout is exceeded, the Logpresso server sends an RPC message to the additional 32 sentries.
The query command outputs the results of RPC response messages in the order they are received. Depending on the load or network conditions of the host where Sentry is installed, the order of the responses may vary with each execution. Use the output data but do not rely on the order of the records.
This query command requires that the input record contains a
guid field value.
|Unique sentry identifier (Not relevant to GUID in JAVA)
This query command returns the fields below in addition to the fields from input record.
|Thread status (
|Execution priority (from 1 to 10, default:
|CPU usage time for the last one second (Unit: nanosecond)
If any error occurs, this query command returns an
_error field in addition to the fields from input record. Possible errors are as follows:
|guid is null
guid field value from input record is null.
|guid should be string
guid field value from input record is not a string.
|guid should be non empty string
guid field value from input record is empty.
|RPC request timeout exceeded
|Disconnected while processing RPC request
|Sentry is not connected.
Depending on the system where the sentry is installed, an RPC exception message other than the above can be issued.
Retrieve the stack status of the thread with the highest CPU usage from all sentries.
