• The Pro.Monitor cockpit administration menu allows to manage global application settings such as:
  • Databases connections and tenant definitions
  • Global settings and logs
  • Applying new updates

This section in accessible only for super admin user.

• After installation, open the application in your browser
• You will be prompted to set superadmin user name and password (if not already set)
• Once you log in, you will be redirected to the superadmin menu.
• You must then configure the following:
  • In DB connectors:
    • Primary configuration database: Holds application and tenants information
    • At least one tenant configuration database
    • At least one tenant metrics database
  • In tenants:
    • At least one tenant with a tenant admin user

Once done, you will be able to log into your first tenant and start configuring the monitoring.

Don't use the same DB name for Primary database and tenant database

Find here below a description of the different sections :

• The configuration database contains sensitive data such as credentials, IP adresses, hostnames, etc…
• Therefore you must pay attention to secure the accesses to the database and the backups
• User credentials are encrypted
• The communication with external parties such as collectors is done via SSL.

• Trusted certificates are located in [PROMONITOR_HOME]/certificates/.keystore
• Application certificate for HTTPS is located into the same file
• You can install or rotate the application certificate by using the below command:
  • keytool -import -trustcacerts -keystore [PROMONITOR_HOME]/certificates/.keystore -storepass agentilKeyStore -noprompt -alias yourAliasName -file [PROMONITOR_HOME]/certificates/[certificate.cer]

Generating a self signed certificate:

# Backup existing keystore
cp /opt/Pro.Monitor-Cockpit/certificates/.keystore /opt/Pro.Monitor-Cockpit/certificates/.keystore.backup
# Convert existing keystore to pkcs12
keytool -importkeystore -srckeystore /opt/Pro.Monitor-Cockpit/certificates/.keystore -destkeystore /opt/Pro.Monitor-Cockpit/certificates/.keystore -deststoretype pkcs12 -srcstorepass agentilKeyStore
# Generate private key and certificate : Use the actual server FQDN as Common Name in the formular.
openssl genrsa  -out domain.key 2048
openssl req -key domain.key -new -x509 -days 1800 -out domain.crt
# Bundle the key and certificate together
openssl pkcs12 -export -in domain.crt -inkey domain.key -name pro_monitor -out ks.p12
# Replace existing certificate
keytool -importkeystore -destkeystore /opt/Pro.Monitor-Cockpit/certificates/.keystore  -storepass agentilKeyStore -noprompt -alias pro_monitor -srckeystore ks.p12
# Restart Pro.monitor service

• You can regularly update superadmin credentials via the superadmin menu.

The promonitor cockpit has been designed for a low maintenance, however, there are few aspects you need to pay attention

• Remove old update files: The update files that you upload in the application are not removed automatically and will consume disk space

In case of major problem with the application, you might need to restore the database.

• Stop promonitor-cockpit service
• Start mysql server
• Get the last backup files
• Then for each backup file, run:
  • mysql -u root -p database_name < database_name.sql

• Restart promonitor-cockpit service

Conditions:

• You can log in as superadmin, but you are not able to connect as a tenant user
• Server log is showing serialization errors or SQL errors
• Stopping and starting promonitor-cockpit service is not solving the problem

Probable cause:

• The tenant configuration is corrupted

Resolution:

• stop promonitor-service
• Use a mysql client and remove the last line of table tenant_configuration
• Depending on the timestamp of the line, you might remove several lines, up to a time you knew the configuration was working
• Once done, start promonitor-service

Conditions:

• It is not possible to log into the application, even in superadmin mode.
• Server log is showing serialization errors or SQL errors

Probable cause 1:

• The server configuration is corrupted

Resolution 1:

• stop promonitor-service
• Use a mysql client and remove the last line of table server_configuration
• Depending on the timestamp of the line, you might remove several lines, up to a time you knew the configuration was working
• Once done, start promonitor-service

Probable cause 2:

• The local server DB is corrupted

Resolution 2:

• stop promonitor-service
• rename local db folder: [PROMONITOR_HOME]/db
• start promonitor-service
• register a new superadmin account
• Recreate the SQL connector to the main DB
• restart promonitor-service
