Enabling SNMP/email alerts

Back to Misc

1. Log in to the Traffic Management Shell (tmsh) by typing the following command:

tmsh

1. To configure the system to send locally generated email messages, use the following command syntax:

modify /sys outbound-smtp mailhub <mail_server>:<port>

1. To save the configuration, type the following command:

save /sys config

1. Optional: If the SMTP mail host supports Secure Sockets Layer (SSL)/TLS authentication but does not establish a secure connection automatically, you must add the following four additional parameters into the /etc/ssmtp/ssmtp.conf configuration file:

UseSTARTTLS=yes
UseTLS=yes
AuthUser=<SMTP-Account-Username>
AuthPass=<SMTP-Account-Password>

1. Verify that ssmtp is configured properly and can send an email message:

echo "ssmtp test mail" | mail -vs "Test email" [email protected]

1. To modify the permissions on the user_alert.conf file to include write access, type the following command:

chmod 644 /config/user_alert.conf

alert BIGIP_SHELL_BP_CONFIGURATION_LOADED { snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.28"; email toaddress="[email protected]" fromaddress="root" body="New configuration loaded" } alert BIGIP_MCPD_MCPDERR_POOL_MEMBER_MON_DOWN "Pool (.*?) member (.*?):(.*?) monitor status down." { snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.10"; lcdwarn description="Node down" priority="1" email toaddress="[email protected]" fromaddress="root" body="A pool member went down" } alert BIGIP_MCPD_MCPDERR_POOL_MEMBER_MON_UP "Pool (.*?) member (.*?):(.*?) monitor status up." { snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.11" email toaddress="[email protected]" fromaddress="root" body="A pool member came back up" } alert BIGIP_MCPD_MCPDERR_NODE_ADDRESS_MON_DOWN "Node (.*?) monitor status down." { snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.12"; lcdwarn description="Node address down" priority="1" email toaddress="[email protected]" fromaddress="root" body="A node went down" } alert BIGIP_MCPD_MCPDERR_NODE_ADDRESS_MON_UP "Node (.*?) monitor status up." { snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.13" email toaddress="[email protected]" fromaddress="root" body="A node came up" }

1. To restore the permissions on the user_alert.conf file, type the following command:

chmod 444 /config/user_alert.conf

1. To restart the alertd process, type the following command:

tmsh restart /sys service alertd
