Room For Improvement

IBM Instana Observability needs enhancements in log management, AI models, user interface speed, support, and cost monitoring.

I had many false positives with IBM Instana Observability. Then I fixed the filters and it became more accurate on the errors reported.
Software engineer at EJADA
One main issue I found with IBM Instana Observability was the customer support, which was very poor when we needed some features to be enabled or integrated into IBM Instana Observability sensors.
DevOps engineer at Yara International
It is not open-source, and I have to be a partner to get more access to the products.
UNIX/LINUX, ENTERPRISE SERVER AND STORAGE ADMINISTRATOR at Fidelity Bank Plc
The only issue I can note is that it's Linux-based, and Linux documentation is not the best.
CTO at Oic
The potential and customization is a little difficult because you have to learn scripts.
Network Engineer at a computer software company with 11-50 employees
 

Setup Cost

Zabbix is praised for being a free, open-source solution with optional low-cost support, attracting enterprise users.
I find the cost of IBM Instana Observability to be very affordable compared to competitors because the pricing mechanism is based on the host that we monitor, unlike other competitors such as DataDog and Dynatrace, whose pricing is based on other factors.
Technical Manager, Consulting at a outsourcing company with 1,001-5,000 employees
It is not that costly, especially since we only use two instances.
Software engineer at EJADA
I think the pricing is good and I do not think it is high.

FranciscoGálvez - PeerSpot reviewer
Technical Manager at a consultancy with 1-10 employees
Observability has improved collaboration and predicts failures across distributed services
From my perspective, IBM Instana Observability is quite technical. Compared to some competitors, it offers an abundance of information about system performance but lacks planning or capacity planning information. You do not receive reports with recommendations; instead, it provides only the technical layer. Other companies, like Compuware, give more functional information about your environment, while IBM Instana Observability provides only limited functional insights. This means you often must interpret the data independently. Unlike other tools that can offer recommendations to save resources or costs, IBM Instana Observability does not provide that functionality. On the bright side, it is much more affordable than some other options, but it isn't complete. If you want full functionality with IBM Instana Observability, you also need to acquire other products for additional insights in monitoring areas, such as networking monitoring tools or similar products. For instance, we often recommend Turbonomic, which provides complementary insights. One potential feature that could improve IBM Instana Observability is the ability to translate KPIs into monetary terms. It would be interesting to have a product that integrates IBM Instana Observability with Turbonomic, as Turbonomic can utilize data from IBM Instana Observability to inform you about unnecessary spending and suggest whether you can consolidate servers or optimize containers for quicker response times. Implementing some level of simulation or capacity planning would greatly enhance the current capabilities of IBM Instana Observability.

Helps reduce response time but has room to improve customization complexity
We are not working on simple standalone solutions like Kaspersky DDoS Protection or Hybrid Cloud Security. Once you understand Zabbix, then it is easy to customize those web pages and graphs for our customer use. It is fully automated to your requirements. Zabbix is working fine with no issues, and I am satisfied with it. We have combined Zabbix and SolarWinds. The integration works fine, and it is easy to integrate Zabbix with the IT environment. We were trying to purchase MDR (Managed Detection and Response), but we are not working on that. I don't have real experience with MDR. We are using Falcon software for that. We are working with Falcon Complete, not with Sandbox. We are not using Kaspersky for business or cloud protection. For that, we are using Zabbix CrowdStrike Falcon Complete solution. I have given this review an overall rating of 8.

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
