Redis

Script to monitor your Redis Server

Agent or SNMP Extend

  1. Download the script onto the desired host

    wget https://raw.githubusercontent.com/librenms/librenms-agent/master/snmp/redis.py -O /etc/snmp/redis.py

  2. Make the script executable

    chmod +x /etc/snmp/redis.py

  3. Edit your snmpd.conf file (usually /etc/snmp/snmpd.conf) and add:

extend redis /etc/snmp/redis.py

SELINUX

(Optional) If you have SELinux in Enforcing mode, you must add a module so the script can get redis informations and write them:

cat << EOF > snmpd_redis.te
module snmpd_redis 1.0;

require {
        type tmp_t;
        type redis_port_t;
        type snmpd_t;
        class tcp_socket name_connect;
        class dir { add_name write };
}

#============= snmpd_t ==============

allow snmpd_t redis_port_t:tcp_socket name_connect;
allow snmpd_t tmp_t:dir { write add_name };
EOF
checkmodule -M -m -o snmpd_redis.mod snmpd_redis.te
semodule_package -o snmpd_redis.pp -m snmpd_redis.mod
semodule -i snmpd_redis.pp

Install the agent on this device if it isn't already and copy the redis script to /usr/lib/check_mk_agent/local/
