Cacti vs ElastiFlow

Cacti is a free, self-hosted network graphing and operational monitoring framework built around RRDtool. It collects data through SNMP object identifiers or scripts, which can retrieve database information or run other code. Availability checks cover SNMP, ICMP, TCP, and UDP. Discovery and automation can create graphs and data sources, while Remote Data Collectors distribute collection and cache data during network interruptions. Graph items support line, area, stacked, horizontal-rule, vertical-rule, print, and comment types. Device templates connect devices with graph templates and data queries, and plugins can extend collection to other protocols, with WMI listed as an example. Role-based management covers users, groups, and domains. Cacti supports SNMP versions 1, 2, and 3, with a documented limitation for advanced SNMPv3 settings such as SHA224+ or AES192+ when PHP SNMP is used. It is available for Linux/Unix and Windows. Installation requires MySQL, PHP, RRDtool, Net-SNMP, and a PHP-capable web server such as Apache or IIS.

ElastiFlow collects and analyzes network flow and telemetry data for network observability and security analytics. Its performance and availability solution is intended to help network operations and engineering teams find and resolve issues across complex, distributed environments. It handles NetFlow, IPFIX, and sFlow, with application visibility, conversation analysis, and bandwidth monitoring. NetObserv offers visibility, open-data-platform integration, pre-built dashboards, and machine-learning jobs. ElastiFlow extracts more than 6,200 standard and vendor-specific fields from flow records and enriches them with GeoIP, autonomous-system, and IP-reputation information. Supported platforms include Elasticsearch, Elastic Cloud, Elastic Cloud Enterprise, OpenSearch, AWS OpenSearch Service, Apache Kafka, Confluent Platform, Redpanda, Splunk, and Cribl Stream. Deployment options include Docker, Linux, Ansible, and Helm. The virtual appliance supports VMware ESX, Proxmox, and KVM, and is intended for up to 16,000 flows per second from one location. Basic costs nothing and supports up to 4,000 records per second and 25 SNMP devices. A 30-day trial is available.
