Maria Connection Errors Test
Sometimes, errors may be detected when connections to the Maria Database server are established. These errors when left unnoticed may causes severe performance bottleneck on the database server. For an improved and enhanced performance of the database server, it is necessary for the administrators to capture errors on the database server and rectify them as soon as they are detected. The Maria Connection Errors helps administrators in this regard!
This test reports the number of hosts connected to the target database server, the various types of errors encountered by the database server. Using this test, administrators can also figure out the percentage of connection errors encountered by the database server.
Target of the test : A Maria Database server
Agent deploying the test : An internal agent
Outputs of the test : One set of results for the Maria Database server being monitored.
Parameter | Description |
---|---|
Test Period |
How often should the test be executed. |
Host |
The IP address of the Maria Database server. |
Port |
The port on which the server is listening. |
Database |
Specify the name of the database that is to be monitored on the target Maria Database server |
User and Password |
The eG agent has to be configured with the credentials of a user who has server-wide PROCESS and SELECT privileges on the monitored Maria Database server. To know how to create such a user, refer to Configuring the eG Agent with Access Privileges |
Confirm Password |
Confirm the password by retyping it here. |
Detailed Diagnosis |
To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:
|
Measurement | Description | Measurement Unit | Interpretation |
---|---|---|---|
Connected hosts |
Indicates the number of hosts that are connected to the database server. |
Number |
|
Connection errors |
Indicates the number of times protocol handshake errors were encountered when hosts were being validated for a connection to the database server. |
Number |
A high value may indicate network connectivity issues with the database server. The detailed diagnosis shows the IP, Host and first seen, last seen, error seen values for a host that faces connection problem with server |
Maximum connection errors |
Indicates the maximum number of times the connections from a host failed and beyond which the host is blocked from contacting the database server. |
Number |
|
Percentage of connection errors |
Indicates the percentage of connection errors that occurred on the database server. |
Percentage |
If this value is high or close to 100, then hosts may not be able to connect to the database server. |
Host blocked connection errors |
Indicates the number of connections that were blocked due to the connections exceeding the Maximum connection errors. |
Number |
|
Transient errors |
Indicates the number of transient erorrs that occurred during IP to host DNS lookups. |
Number |
|
Permanent errors |
Indicates the number of permanent errors that occurred during IP to host DNS lookups. |
Number |
|
Host name format errors |
Indicates the number of hostname format errors. |
Number |
|
Reverse lookup DNS errors |
Indicates the number of errors that occurred during DNS reverse lookups. |
Number |
|
Host not privileged errors |
Indicates the number of errors that were captured due to the users from the host are not permitted to login. |
Number |
|
Authentication errors |
Indicates the number of errors that were captured due to authentication failures. |
Number |
Authentication failures generally occur when incorrect username or password is provided to connect to the database server. The detailed diagnosis of this measure lists the IP, Host and first seen, last seen, error seen values. |
Authentication plug-in errors |
Indicates the number of errors that were reported by an authentication plugin. |
Number |
|
Handshake errors |
Indicates the number of errors that were detected at the wire protocol level. |
Number |
|
Proxy users errors |
Indicates the errors that occurred when a proxy user of a user that does not exists tries logging in. |
Number |
|
Max user authentication errors |
Indicates the maximum number of times authentication errors were detected for a user after the quota of that user exceeded the tries. |
Number |
|
Default database errors |
Indicates the number of errors that occurred due to the user not having required permission to access the default database. |
Number |
|
Local errors |
Indicates the number of local server errors such as out-of-memory errors, unrelated to network, authentication, or authorization errors detected. |
Number |
