Measurement
Unit |
Interpretation |
| Local_tx_begun_rate
|
Indicates the
rate at which the local transactions begin at the server. |
Trans/Sec
|
A high value indicates an increased overload on the server.
|
| Active_local_tx
|
Indicates the
average number of concurrently active local transactions. |
Number
|
If the value of this measure is high, it signifies greater load on the
server. This might increase the number of waiting local transactions.
|
| Local_tx_duration
|
Indicates the
average duration of the local transactions. |
Secs
|
A high transaction duration value indicates increased load on the
server.
|
| Local_commit_duration
|
Indicates the
average duration of commit for local transactions. |
Secs
|
If the total time taken for committing a local transaction is high,
then it indicates a bottleneck on the server.
|
| Local_tx_commit_rate
|
Indicates the
rate at which the local transactions are being committed. |
Trans/Sec
|
If the rate of transactions that are being committed is very high, it
signifies load on the server. It might be caused when some locked
transactions are released suddenly.
|
| Local_tx_rolled_back_rate
|
Indicates the
rate at which the local transactions are being rolled back. |
Trans/Sec
|
A high value indicates a problem with the application. Possible
reasons could be the problem with application or with some other
dependent server (e.g. Database).
|
| Local_tx_timedout_rate
|
Indicates the
rate at which the local transactions are being timed out. |
Trans/Sec
|
Again, a rise in the value could be due to the problem with the
application or with some other dependent server like the database.
