Install SNMP with RedHat or CentOS
Configure the BigPanda agent to send monitoring alerts from SNMP.
The BigPanda agent is a low-footprint utility installed on the master host of your monitoring tool. It consumes alerts from the tool in real-time and then transmits them to BigPanda via TLS-encrypted HTTP calls.
Python Compatibility
To use the Open Integration Manager for Agent-based integrations, Python version>= 3.8.0 and an Agent version >= 10.2 are required.
Prerequisites
python >= 3.8.0 is required for the latest version of the BigPanda Agent, and will be installed by the BigPanda Agent installer if it does not exist.
-
Ensure python3 is installed with the following command:
$ sudo yum install -y python3
-
Verify the install with the following commands:
$ python3 --version $ pip3 --version
Note: If pip3 was not installed as a dependency, it can be installed with sudo yum install -y python3-pip
.
Note: Access to JFrog, pypi, and yum repositories are required to install all dependencies.
Install the BigPanda Agent on RedHat or CentOS
-
Add a new yum repository to download the BigPanda agent and BigPanda snmpd packages:
$ sudo vim /etc/yum.repos.d/bigpanda.repo ... [BigPanda] name=BigPanda baseurl=https://bigpandaio.jfrog.io/artifactory/int-rpm/bigpanda/agents/ enabled=1 gpgcheck=0 gpgkey=https://bigpandaio.jfrog.io/artifactory/int-rpm/bigpanda/agents/repodata/repomd.xml.key repo_gpgcheck=1
-
Update the yum repos list to add the BigPanda repo.
$ sudo yum update
-
List all available packages with duplicates in the BigPanda repo.
$ sudo yum list --showduplicates bigpanda* | expand This system is not registered with an entitlement server. You can use subscription-manager to register. Available Packages bigpanda-agent.x86_64 9.0.1-1.el7 BigPanda bigpanda-agent.x86_64 9.0.1-1.el8 BigPanda bigpanda-agent.x86_64 9.1.0-1.el7 BigPanda bigpanda-agent.x86_64 9.1.0-1.el8 BigPanda bigpanda-snmpd.x86_64 3.1.0-1.el7 BigPanda bigpanda-snmpd.x86_64 3.1.0-1.el8 BigPanda
Note: RHEL or Centos does not send the OS version to JFrog, so we need to cherrypick the correct version for the OS.
-
Install the BigPanda agent and snmpd packages.
$ sudo yum install bigpanda-agent-<version-number> $ sudo yum install bigpanda-snmpd-<version-number>
Note: Append the version number to the package name, (i.e.
bigpanda-agent-9.1.0-1.el7
).
Configure the BigPanda Agent
-
Configure the agent to work with the Raw Alerts Transfer plugin by running the following commands:
$ sudo bigpanda-config --init --token <Your Org Bearer Token> $ sudo bigpanda-config --add rawalertstransfer --app-key <Your App Key>
Configure the BigPanda SNMP Agent
-
If any MIBs are not included by default, they need to be compiled and added manually:
$ cd /opt/bigpanda/bigpanda-snmpd/mib_compiler $ sudo ./compile_mib.sh --input-directory <path to MIBs> --output-directory /etc/bigpanda/snmpd/conf/
-
Modify Config Files
For MIBs that are to be monitored, their respective Event Configuration files must be added to the bigpanda-snmpd configuration file:
Edit
/etc/bigpanda/snmpd/snmp-daemon.json
, and add the paths to the event_config files to theprocessing.event-configs
array.For example:
$ sudo vi /etc/bigpanda/snmpd/snmp-daemon.json ... { <snip> "processing": { "mibs-dir": "/etc/bigpanda/snmpd/mibs", "event-configs": [ event_configs/example.json, <ADD EVENT CONFIGS HERE> ], "target-dir": "/var/lib/bigpanda/queue", "stress_test": false } </snip> }
Start the Services
-
Start the BigPanda agent and snmpd services by running the following commands:
- For RHEL or Centos 7 and RHEL or Centos 8:
$ sudo service bigpanda start $ sudo service bigpanda-snmpd start
- For RHEL or Centos 7 and RHEL or Centos 8:
-
Verify the agents have started:
$ systemctl status bigpanda $ systemctl status bigpanda-snmpd
Troubleshooting
- You should have the snmpd directory with the
snmp-daemon.json
config file located at/etc/bigpanda/snmpd/snmp-daemon.json
. - If the configs are missing or the package did not set up correctly, remove the package and reinstall.
$ sudo service bigpanda stop
$ sudo service bigpanda-snmpd stop
$ sudo yum reinstall -y bigpanda
$ sudo yum reinstall -y bigpanda-snmpd
Test the Integration
-
Install SNMP Utils:
$ sudo yum install -y net-snmp-utils
-
Send the test SNMP v2 trap:
$ sudo snmptrap -v 2c -c public 127.0.0.1:5000 1 1.3.6.1.2.1.1 1.3.6.1.2.1.1.5 s "production-switch-1" 1.3.6.1.2.1.1.1 s "SNMP trap test"
Note: Since it is a test message, it won’t be resolved automatically. Click Resolve incident in the BigPanda UI to manually resolve it.
-
Set up the config file to receive SNMP v3 traps:
- Note: Network discovery must be performed to capture the engine id and user details prior to testing SNMP v3.
- Add the security object to the snmp config file:
/etc/bigpanda/snmpd/snmp-daemon.json
.
Note:"security": { "local_engine_id": "8000000001020304", "users": [ { "username": "panda", "level": "authPriv", "auth_protocol": "usmHMACSHAAuthProtocol", "privacy_protocol": "usmAesCfb128Protocol", "auth_key": "snmpauthpass123", "privacy_key": "snmpkeypass123", "engine_id": "8000000008675309" }, { "username": "new-panda", "level": "authPriv", "auth_protocol": "usmHMACSHAAuthProtocol", "privacy_protocol": "usmAesCfb128Protocol", "auth_key": "snmpauthpass123", "privacy_key": "snmpkeypass123", "engine_id": "8000000008888888" } ] },
local_engine_id
is the local client’s engine id, and can be omitted. This engine id is generated in memory if not provided.
-
Send an SNMP v3 test trap:
$ sudo snmptrap -v3 -e 0x8000000008675309 -u panda -l authPriv -a SHA -A snmpauthpass123 -x AES -X snmpkeypass123 127.0.0.1:5000 "" 1.3.6.1.2.1.1 1.3.6.1.2.1.1.5 s "production-switch-v3" 1.3.6.1.2.1.1.1 s "SNMP v3 trap test"
