The State of Alerting in the IT Ops world
OnPage Corp. just finished a survey of more than 100 ITOps professionals from across the United States. Our goal was to acquire a greater understanding of how well engineers in the industry are performing when it comes to critical alerting and alert management of their IT teams.
We wanted to understand the antecedents of alert fatigue for ITOps that appear earlier in the food chain. We also wanted to see how many alerts teams receive per day as well as who gets alerted. We wanted to understand how alerts are managed. And, we wanted to see how well teams analyze their actions and take those lessons forward.
In many ways, the survey was successful. We received a large number of responses from a number of industries and acquired a strong sense of how ITOps is performing across the country. Unfortunately, we also saw that for all the Chaos Monkeys and strides toward improved response to alerting, there is still a significant lack of progress.
What’s All the Buzz About?
Automated alerting is an essential component of monitoring. Automated alerts are what allow teams to receive automatically generated alerts from multiple points along their IT stack and software. In theory, this multitude of alerts is what enables teams to more quickly identify the causes of a problem and minimize the severity. The hope is, that with early recognition of the issue, engineers will be able to minimize service degradation and disruption.
But alerts aren’t always as effective as they could be or need to be. Real problems often are lost in a sea of noisy alarms. As our survey showed, this is because teams are inundated with alerts coming in via multiple formats. Moreover, the barrage of alerts leaves teams inundated and practically unable to cope.
The Law of Above Average
Our survey showed that more than 80 percent of IT teams are alerted to critical incidents via email. General best practices would dictate that email is fine for daily communication inside a business. However, for critical incidents, email is less than ideal, as it allows critical incidents to get buried under a pile of other emails. There is no way for critical issues to rise to the top of the pile.
Since our questions were multiple choice, respondents could provide multiple answers with regard to how they received notice of critical incidents. So, while email was the most prevalent form of communication, individuals indicated that they are also simultaneously receiving alerts by SMS or phone call. Our survey showed that 58.9 percent and 51.4 percent of respondents received alerts via these methods.
Already from this nugget of information, we see the opportunity for both information overload and an opportunity for missed alerts. By simultaneously receiving alerts through multiple formats, the level of irritation and overload inevitably rises. At the same time, if emails are the only form in which IT professionals receive alerts then there is a high opportunity to miss alerts all together.
How Many Alerts Was That?
The survey results also indicated that just over 41 percent of ITOps receive 11 alerts or more per day. Additionally, just over 20 percent of this group received 40 alerts or more per day. While 40 alerts is clearly more than a team can reasonably manage or should manage, this figure also goes a long way toward explaining why some alerts just get missed. If more than 40 alerts are sent to you and your team every day, it becomes very difficult to prioritize alerts and determine which should be handled first.
Perhaps to better manage this large number of alerts, many teams use escalation procedures. Our survey showed that 76.6 percent of respondents have some sort of escalation procedure in place. At the same time, the most frequent ways to escalate critical responses was through email or SMS.
The conclusions one can draw from these numbers are that, despite the large number of papers written on improving alert management, many ITOps have not been able to achieve this end. While our survey did show that just shy of 59 percent receive a manageable number of alerts, 41 percent are inundated.
Not Just Intelligence, Business Intelligence
Perhaps analysts of the industry could be more optimistic if they saw that teams were using analytics to track how well they are performing. If teams employed analytics, they would be better able to review their progress, see where they are failing to meet the grade and then embark on routines to improve. Unfortunately, this is not the case.
When asked whether their team has employed any type of business intelligence to review and analyze their team’s performance, more than 70 percent reported that they did not subscribe to any BI platform. The problem with this result is more than just a missed opportunity; it is also the loss of opportunity to fundamentally improve the business at many levels.
One of the most important reasons why you need to invest in an effective BI system is because such a system can improve efficiency within your organization and, as a result, increase productivity. Effective business intelligence can also improve the decision-making processes at all levels of management and improve your tactical strategic management.
Yet by forgoing investments in these BI tools, teams are failing to investigate their processes and methods that would improve their team and minimize alert fatigue.
A Call for Smart Alerting
The lesson can be drawn from this is that companies don’t necessarily need more alerting. What they do need is to shift toward more smart alerting.
Smart alerting means that not every bump on the monitoring screen gets tied to an alert. Instead, monitoring output is calibrated so that possibilities are aligned with probabilities and impacts. Alerts also get sent to the teams or individuals that are best able to manage the issue. Additionally, alerts are actionable and come with instructions regarding what the problem might be.
Smart alerting also means that teams use business intelligence tools such as reports and graphs and charts to determine which of their practices have been effective or not effective. Without this insight, teams are often unaware of the subtle points that could really impact their team and provide them with a way to improve their output.
There are a number of insights that can be garnered from our survey. I encourage you to take a moment and download a copy of the study and see what you can learn that will help your team.
