Recommended MMR

User Requests seen by service

Rate - Input traffic volume in different time intervals

AVG

business transactions being completed successfully

Rate – for Output traffic volume in different time intervals (aka application-throughput)

Error counts by http-response code value

Error – for requests ended in errors

Response Latency

Latency - in milliseconds noticed in Service responses. Should be measured in percentiles. P99 means 99% of requests are experiencing this much latency

AVG

500ms (Based on historical data from DOM app)

Requests time spent in wait queues

Saturation – indicated by long wait times spent in service input queues

AVG

Resource (cpu, memory, disk) utilization percentages¹

Saturation – indicated by persistent spikes in resource usage

request latency times

how long it takes to start processing a request after the user has sent it, in different load situations.

NA

The number of concurrent users

versus

the average response time

how long it takes to complete a request after it has started processing, in different load situations

Oracle DB Status

Oracle Status – helps to notify whether the database is running or not

Down

A job's execution can fail for any of several reasons, including incorrect input, storage or memory quota issues, timeouts, or database connection problems.

Failed Jobs – number of jobs failed, either by throwing an error or by abnormally terminating

5

the maximum number of Operating System (OS) user processes that can simultaneously connect to the Oracle database at the same time

Process Usage Percentage – saturation of Oracle DB process

70

This metric checks for the number of failed logins on the target database

Failed Login Count- the number of failed logon attempts

3

the time spent in database operations per transaction

Response Time – response time (ms)

200ms

specifies the maximum number of sessions used by the database

Sessions Usage – in percentage (%)

30%

The metrics active_sessions and inactive_sessions denotes the number of active and inactive sessions respectively

Active and Inactive Sessions  

5

Know your tablespace_status to be either Read-Write, Read-Only or Offline. tablespace_usage_percent helps track how data grows in the database and to make sure appropriate provisioning is given

Tablespace Status and its Usage (in %) -  

High – 90 %

Warning – 80 %

The reads and writes represent the number of physical reads and writes respectively. A total of the reads and writes gives the I/O activity for a specific disk.

Number of Reads & Writes in a Tablespace

10

The rman_failed_backup_count provides the number of failed backups in the RMAN repository

RMAN Failed Backup Count – backup status

5

High Disk Write Utilization [Disk mount point will change but physical write to DB needs to be included]

Percentage of Physical Write Utilization

85%

Service Availability – checks if the application is online or not

Down

SSL-Cert Expiry – it checks for number of days remaining until certificate expired

High – Less than 5 days left

Warning – Less than 10 days left

Page load behavior – emulates a ‘page visit’ using Google Chrome agent.

Any broken link on a page – reports individual non-successful links that caused a failure.
