GlusterFS vs Ceph performance – Let’s discuss it in detail!!

GlusterFS vs Ceph performance – Which distributed storage management package performs best?

Open-source storage platform offers many management packages including GlusterFS and Ceph. Let’s see what makes them different from each other.

As part of our Server Management Services, we help customers in choosing the right storage manager.

Today, we’ll do an analysis of GlusterFS vs Ceph performance and see what our Support Engineers suggest to our customers.

ACK scan DOS attack – How to mitigate

Wondering how to mitigate ACK scan DOS attack? We can help you.

ACK scans are generally used to identify ports or hosts that may be filtered and resistant to any other form of scanning. An adversary uses TCP ACK segments to gather information about firewall or ACL configuration.

Attackers scan our router or send unwanted traffic/requests like SYN, ACK, FIN to specific UDP/TCP Port. Sometimes, they also send continuous unwanted traffic into particular open port/s. This can crash our router and make it out of service.

Here at Bobcares we often handle DOS attack as a part of our Server Management Services.

Today let’s see some of the steps which our Support Engineers follow to mitigate this issue.

Troubleshoot Redis latency problems – How we do it

Wondering how to troubleshoot Redis latency problems? We can help you.

The processing time for Redis is normally low. But certain conditions at times create latency problems in Redis.

Latency is the maximum delay between the time a client issues a command and the time the reply to the command is received by the client.

As a part of our Server Management Services, we help our customers to fix Redis-related errors regularly.

Today let’s discuss the steps which our Support Engineers follow to troubleshoot Redis latency problems.

Manage KVM guest virtual machines using virsh commands

Wondering how to manage KVM guest virtual machines using virsh commands? We can help you.

Virsh is a management user interface for virsh guest domains. It can be used to create, pause, restart, and shutdown domains. In addition, it can be used to list current domains available in our Virtualization hypervisor platform.

Virsh interacts with Libvirt which is a library aimed at providing a long-term stable API. It currently supports Xen, QEMU, KVM, LXC, OpenVZ, VirtualBox, and VMware ESX.

Here at Bobcares we often use virsh commands to manage KVM guest virtual machines of our customers.

Today let’s see how our Support Engineers use Virsh commands as a part of our Server Management Services.

Perfmon counters for Disk Usage – Top Perfmon counters

Wondering how to use Perfmon counters for Disk Usage? We can help you.

Problems regarding Disk I/O are usually difficult to diagnose and debug. Perfmon disk counters help us to diagnose disk issues.

Here a Bobcares, we use perfmon counters as a part of our Server Management System for our customers using SQL.

Today let’s see some top performance counters to identify SQL server disk bottleneck.

Perfmon Counters for memory usage – Top perfmon counters

Wondering how to use Perfmon Counters for memory usage? We can help you.

Memory is one of the important system resources that SQL Server uses to process their transactions. Sometimes, the server will face memory issues which in turn reduces the performance of running transactions.

We can use Windows PerfMon utility to gather current values of all given performance counters. This will help us to get a better understanding of the memory usage in the server.

Here a Bobcares, we use perfmon counters as a part of our Server Management System for our customers using SQL.

Today let’s see some top performance counters to identify SQL Server Memory pressure.

ICMP Flood Attack – How to Mitigate

Wondering how to mitigate ICMP Flood Attack? We can help you.

Ping flood, also known as ICMP flood, is a common Denial of Service (DoS) attack in which an attacker takes down a victim’s computer by overwhelming it with ICMP echo requests, also known as pings.

When the attack traffic comes from multiple devices, the attack becomes a DDoS attack.

Here at Bobcares, we often handle such DDoS attacks as apart of our Server Management Services.

Today let’s see the steps our Support Techs follow to mitigate this.

Push Notification using Firebase Cloud Messaging – How to setup

Need to setup Push Notification using Firebase Cloud Messaging(FCM)? We can help you.

We know that Push notification is one of the effective ways to increase user engagement and bring more traffic to the website.

However, if push messages pop up every now and then it may not help so we have to find a way to send push messages in a timely manner. For this, we can use FCM.

Here at Bobcares, we get requests from our customers to set up push notifications as a part of our Server Management Services.

Today let’s see how our Support Techs set up push notifications using Firebase.

DNS Amplification Attack – How to Mitigate

Wondering how to mitigate DNS amplification attack? We can help you.

We know that DDoS tries to deny the important services that run on the server by sending enormous traffic to the destination server so that the server can’t handle them.

DNS amplification is a Distributed Denial of Service (DDoS) attack in which the attacker exploits vulnerabilities in domain name system (DNS) servers to turn initially small queries into much larger payloads, which are used to bring down the victim’s servers. So it is important to protect servers from DDoS to avoid server downtime.

Here at Bobcares we often handle DDoS attacks as a part of our Server Management Services.

Today let’s see how our Support Engineers mitigate DNS Amplification Attack for our customers.
