As we promised in our previous blog Prometheus as Scale – Part 1 that in our next blog we will be writing about the implementation part of Cortex with Prometheus, so here we are with our promise. But before going to the implementation part, we would suggest you guys go through our first blog to know the need for it.
Previously we talked that Prometheus is becoming a go-to option for people who want to implement event-based monitoring and alerting. The implementation and management of Prometheus are quite easy. But when we have a large infrastructure to monitor or the infrastructure has started to grow you require to scale monitoring solution as well.
A few days back we were also in a similar kind of situation where one of our client’s infrastructure was growing as per the need and they need a resilient, scalable, and reliable monitoring system. Since they were already using the Prometheus, so we explored our option and came across an interesting project called “Cortex“.
Today we had an interesting problem for a project. We were getting the message ‘disk is full’ despite having plenty of free space. Luckily my first thought was ‘inodes?’
I logged in and checked inode usage
| $ df -i Filesystem Inodes IUsed IFree IUse% Mounted on /dev/xvda1 525312 524844 468 100% / tmpfs 1007942 1102 1006840 1% /run |
This shows that all the inodes on the disk itself are full.
High inode usage is usually caused by a massive number of small files. In this case, the session files are normally stored somewhere temporary and removed when not in use. Either there could have been a bug in the code not removing them or it was a higher traffic website.
So we can see that inode is a very important aspect of Linux, so this blog will take u to a detailed journey to inodes.
When securing hosted resources in the cloud, it’s crucial to employ robust methods to protect against unauthorized access and potential threats. Among these methods, security groups play a pivotal role in safeguarding our EC2 instances.
Amazon Web Services (AWS), a leading cloud provider, offers a multitude of services, including EC2 (Elastic Cloud Compute), which allows us to create and manage instances. Continue reading “Security Group Strategy for AWS”
Cloud migration and application modernization have become essential for businesses that aim for greater agility, scalability, and cost savings.These strategies represent a significant change in the way organizations develop, deploy, and manage their applications.However, simply moving applications to the cloud or rewriting them without adjusting underlying processes can waste opportunities and increase complexity.
