- DSPHtpEventCollector is a data source for Syslog as well as HTTP clients.
- DSP Gather connectors that can retrieve information from a wide variety of sources, including Azure, Amazon S3, Amazon CloudWatch, and more. The collectors gather information by means of scheduled jobs.
- Data sources like Google Cloud Pub/Sub, Apache Pulsar, Apache Kafka, and others are ingested by steaming connections. The sources constantly emit data, which these connectors receive.
The open-source data visualization as well as tracking software Grafana is available simultaneously. Its primary function is to offer visual depictions of measurements. It can access data from many sources using a query language similar to SQL, and it is able to link to InfluxDB, Elasticsearch, Prometheus, and more.
Grafana gathers data from particular sources and displays it visually, but Splunk is more flexible and intended to serve as a repository for every piece of data.
Visualizing Data:
With their respective sets of visualization features, Kibana & Grafana are both excellent options.
The amount of bandwidth needed to set up the dashboards as well as panels in Grafana depends on the metrics you want to display. By choosing a data source before merging panels from other sources, you may construct a robust dashboard.
You can change the layout, graphics, colors, and more of your Splunk dashboards using the dashboard studios that Splunk provides.
Alerts and Reminders:
You can set circumstances and thresholds to generate alerts with Splunk’s powerful alerting features. The built-in alert manager enables users to handle and monitor many sources of notifications in one place. Alerts can be issued through various channels, including Slack, PagerDuty, ServiceNow, SMS, and email.
For continuous monitoring and notifications, Grafana comes with an integrated alert management. Several notification channels, including email, Slack, etc., can be set up to send alerts depending on circumstances and criteria. The ability to build alerting rules at the dashboard’s panel level in Grafana simplifies the setup and management of alerts for individual data sets.
Splunk and Grafana both have powerful features, but Grafana gives you finer control over alert rules on a panel level whereas Splunk has better alert handling and tracking.
