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 MariaConStatTest 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.

Measurement	Description	Measurement Unit	Interpretation
Host_connected	Indicates the number of hosts that are connected to the database server.	Number
Connection_error	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
Max_connection_error	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
Conn_error_percent	Indicates the percentage of connection errors that occurred on the database server.	Percent
Hostname_format_error	Indicates the number of hostname format errors.	Number
Host_blocked	Indicates the number of connections that were blocked due to the connections exceeding the Maximum connection errors.	Number
Reverse_lookup	Indicates the number of errors that occurred during DNS reverse lookups.	Number
Host_not_prev_error	Indicates the number of errors that were captured due to the users from the host are not permitted to login.	Number
Auth_error	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.
Auth_plugin	Indicates the number of errors that were reported by an authentication plugin.	Number
Max_user_auth	Indicates the maximum number of times authentication errors were detected for a user after the quota of that user exceeded the tries.	Number
Handshake	Indicates the number of errors that were detected at the wire protocol level.	Number
Proxy_user	Indicates the errors that occurred when a proxy user of a user that does not exists tries logging in.	Number
Default_db_error	Indicates the number of errors that occurred due to the user not having required permission to access the default database.	Number
local_error	Indicates the number of local server errors such as out-of-memory errors, unrelated to network, authentication, or authorization errors detected.	Number
Transient	Indicates the number of transient erorrs that occurred during IP to host DNS lookups.	Number
Permanent_error	Indicates the number of permanent errors that occurred during IP to host DNS lookups.	Number
