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…

Has vastly increased our ability to reach SLA targets consistently
Scalability could be improved. We are using it through the IBM cloud deployment and on some of the data centers that are very heavily used, there is a significant lag in the event stream, sometimes 10, 15 minutes behind, which makes the RCA impossible. If an event hits but you don't have the information to look at it, then it's tricky. This is probably not an issue of the product itself, but more a deployment issue. There is something on the IBM side that needs some readjustment to make certain these lags don't happen too often. We now use other tools for back-up in that area. But if you really want to do SIEM type work, then that is an aspect that needs some improvement. It's hard to tell if it's the product or the IBM deployment of it. The user interface is really very productive interactively but for an additional feature, it would be nice if we somehow could encapsulate a query or a filter, and communicate or share that among the team so that specific types of actions can be carried out quickly. In particular, when we deal with a customer issue, it may pertain to a particular transaction through the system and each transaction has a unique ID. It would be great if we could query that ID and request all transactions that pertain to a specific ID. For now, we need to find the events, then extract the ID. Once we have that, we can go through the UI to set up the query and filter it to give us a transaction. But it would be really nice if we could simply say, "Here's the ID. Give me all the transactions."

Quotes from Members

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

Pros

"The effectiveness of filters is pivotal for optimizing the search process and extracting the specific information we need from the extensive log data."
"The most valuable features of the solution stem from the fact that it is an open-source tool that is stable and flexible."
"Grafana Loki is easy to monitor and detect errors."
"The tool can be used in multi-cluster environments."
"Grafana agent is very lightweight and does not cost significant resources of our cluster."
"The most valuable feature of the solution is the tool's GUI. The solution's GUI is very user-friendly."
"The most valuable part of Loki is the ability to filter logs by keywords and devices."
"We are using Grafana Loki as a database for real-time metrics."
"LogDNA consolidates all logs into one place, which is super valuable."
"The solution aggregates all event streams, so that if there are any issues, it's all in the same interface."
 

Cons

"The product must improve its UI."
"The correlation of requests is not simple in Grafana Loki and can be improved."
"The solution's scalability depends on the team managing the Grafana instance."
"We face some bugs when we install the latest version of Grafana Loki."
"It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers."
"It's not intended for proprietary services, so you have to struggle with configuration a lot."
"We encountered certain limitations when it came to alerting, particularly when dealing with specific data sources."
"Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring."
"Every once in a while, our IBM cloud operational implementation gets behind. Sometimes, when we have a customer event, we do not get access to the latest logs for about 30 minutes, particularly for the sites that are heavily utilized. This is clearly not good. It is impossible to RCA when you can't look at the logs that pertain to the time period in which the event occurred. It could be more of an operational problem than a feature problem. I don't have visibility about whether it is a LogDNA issue or just an operational issue."
"No ability to encapsulate a query or a filter, and communicate or share that among the team."
 

Pricing and Cost Advice

"The solution is open source."

"I use the solution's open-source version. Grafana Loki is a completely free solution for me."
"I use the open-source version of the product."
"The pricing structure varies based on the number of users; there might be specific taxes to pay for it."

"Since we are using the open-source version of Grafana Loki, we are not paying anything for the solution."
