Efficient log filtering enhances quick network troubleshooting
We use Grafana Loki for various verticals including manufacturing, finance, health, and aerospatial sectors. It primarily helps in monitoring security and access to devices. Grafana dashboards are used to track access success and failure and audit commands issued on devices Loki significantly…
Ivan Kokalovic - PeerSpot reviewer
Facilitates backend service monitoring with efficient log retrieval and API flexibility
Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline. It boosts the knowledge of sales and customer support teams by allowing them to see the backend operations without needing to read the code. Its API is flexible for visualization, and its powerful search engine efficiently handles large volumes of log data. Moreover, its stability, fast search capabilities, and compatibility with languages like ANSI SQL enhance its utility in IT infrastructure.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The product's most valuable features are ease of installation, management, and reporting. It has an efficient ability to set thresholds for alerts, as well."
"The tool can be used in multi-cluster environments."
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"The best feature of Grafana Loki is that it integrates well with our other tool."
"The most valuable part of Loki is the ability to filter logs by keywords and devices."
"Grafana Loki is easy to monitor and detect errors."
"Loki also utilizes the same service discovery mechanism as used by Prometheus. So, whatever labeled metadata you see in Prometheus, you have the exact same metadata in the Loki system. Given this level of intricacy and the attempt to address these challenges, I firmly believe that Loki deserves praise for the work."
"The most valuable feature of Grafana Loki is the dashboards which are really simple to create."
"Graylog is very handy."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"I like the correlation and the alerting."
"The product is scalable. The solution is stable."
"Open source and user friendly."
 

Cons

"There is a need for some change in the alerting types of the product. In short, a few changes in the alert area are needed due to minor shortcomings."
"We face some bugs when we install the latest version of Grafana Loki."
"The platform's stability needs improvement."
"My main concern is the recommended production-grade setup. They suggest using tools like Tanka or Jsonnet. They should simplify the process to increase adoption."
"The solution has shortcomings regarding security monitoring-oriented features that need improvement."
"It's not intended for proprietary services, so you have to struggle with configuration a lot."
"The solution's scalability depends on the team managing the Grafana instance."
"Visualization-wise, Grafana Loki's dashboard looks a little outdated compared to other open-source visualization tools like Chronograf."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"More customization is always useful."
"Dashboards, stream alerts and parsing could be improved."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"Over six months, I had two similar issues where searches were performed on field "messages". It exhausted all the memory of the ES node causing an ES crash and a Graylog halt."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"I would like to see some kind of visualization included in Graylog."
