We invited OpenNMS employees to share their own experiences in ICT as women, non-binary, those identifying as female, or allies. Read their stories. International Girls in ICT Day celebrates the importance of girls and women in the information and communications technology sector. Since 2001, the International Telecommunication Union (ITU), a United Nations agency, has sponsored [...]
Submitting issues, fixing bugs, contributing features, enhancements, and extensions, writing documentation, or reporting security issues are all valuable ways that our community helps make OpenNMS a better monitoring platform. OpenNMS uses Jira to manage issue tracking and development. Once you have a Jira account and have signed the OpenNMS Contribution Agreement (OCA), you can start [...]
We recently migrated our documentation to Antora. Learn more about how we did it: the good, the bad, and the technical.
If you use Provisiond to populate all or part of your node database, you may want to define how data is stored so that it remains in the same directory even if a nodeID changes. Mark Mahacek, Senior Application Support Engineer at The OpenNMS Group, shares how to do this in Storing data with foreign sources [...]
The OpenNMS Minion includes useful, built-in commands to verify configuration and debug access to management agents. In this Discourse article, Ronny Trommer, Community/Product Manager at The OpenNMS Group, shows how to test connectivity with the Minion, perform a health check, execute a remote ping to arbitrary FQDNs or IP addresses, execute remote DNS lookups, run SNMP [...]
If you look at the OpenNMS documentation, you’ll notice a change. Yes, it has a more polished appearance thanks to our new corporate branding, but it also has improved content and functionality as a result of our recent migration from AsciiDoctor to Antora for building the documentation. Migrating the documentation was a huge undertaking (we’ll [...]
Large, distributed networks can be difficult to reach and monitor from a central location, with challenges like firewalls, network address translation (NAT) traversal, overlapping IP address ranges, and locked-down environments. The OpenNMS Minion component extends the reach of Horizon/Meridian, so you can monitor systems and networks that would otherwise be inaccessible, for optimal visibility into every [...]
When you want to store large amounts of non-aggregated data (such as performance metrics), the round robin database (RRDtool) in OpenNMS may not be enough. OpenNMS provides a time-series data store (Newts) that works with Apache Cassandra or ScyllaDB to group metrics for more efficient storage and retrieval. It removes aggregation as a bottleneck to storage, [...]
Based on Horizon 26.1.3, here’s a preview of some of the features we’re excited to bring to Meridian 2020: Enriched Flows, Better Messaging with Kafka Configure flows to include node metadata before forwarding to Kafka so that you can aggregate flow data or integrate it with your own custom database to persist all flows. New Kafka [...]
The problem: Device design prevents auto-discovery Windstream deploys Calix C7 Multiservice Access Systems (C7s) in its network. C7s work in clusters, where all members of the cluster share the same IP address. Data collection from C7s is complicated, as each device has multiple internal SNMP agents, each of which has its own credentials and settings, all [...]
