If the command executes successfully, SNAplus2 returns the following parameters:
alerts_sent
Number of locally originated alerts sent using the MDS transport system.
alert_errors_rcvd
Number of error messages received by MDS. An error message indicates a delivery failure for a message
containing an alert.
uncorrelated_alert_errors
Number of error messages received by MDS. An error message indicates a delivery failure for a message
containing an alert. Delivery failure occurs when the error message cannot be correlated to an alert on the
MDS send alert queue. MDS maintains a fixed-size queue where it caches alerts that were sent to the problem
determination focal point. When the queue reaches maximum size, the oldest alert is discarded and replaced
by the new alert. If a delivery error message is received, MDS attempts to correlate the error message to a
cached alert so the alert can be held until the problem determination focal point is restored.
Note
The two counts alert_errors_rcvd and uncorrelated_alert_errors can be used to check
that the size of the send alert queue (specified on the define_node command) is
appropriate. If the value of uncorrelated_alert_errors increases over time, the size
of the send alert queue is too small.
mds_mus_rcvd_local
Number of MDS_MUs received from local applications.
mds_mus_rcvd_remote
Number of MDS_MUs received from remote nodes using the MDS_RECEIVE and MSU_HANDLER
transaction programs.
mds_mus_delivered_local
Number of MDS_MUs successfully delivered to local applications.
