Performing maintenance is never fun. It’s time consuming, and sometimes issues might arise during maintenance that make you want to pull your hair out. Regardless, to maximize uptime, we all have to do it from time to time. Whether we are talking about IT infrastructure or automobiles, it’s just something that has to be done. In the context of IT infrastructure, whether you are fixing a hardware issue or just performing regular maintenance like patching or upgrade, it’s a necessary evil. There are a few things you need to consider when you are performing maintenance on your servers and devices when you have a monitoring solution in place.
If you know you have to bring your car(s) into the shop for repair, you would clear your calendar and not make any plans because you won’t be able to go anywhere. Similarly, if you have to bring your servers down for maintenance, you know they won’t be working as they normally would. You know your monitoring solution will cause a “sea of red” and send out tons of alerts. Life does not have to suck. You can schedule maintenance in up.time so that alerts will not be triggered during the maintenance window. If you have to bring systems down for an emergency, you can also do it in an ad-hoc manner as well.
Accuracy of SLA
If you are measuring Service Level Agreements (SLAs) in your environment, most likely you won’t want to count maintenance against your SLA. Most maintenance times are scheduled.therefore, frequency of maintenance is something that you and your customer had agreed on. If scheduled maintenance decreases your SLA, it will skew the actual expected availability. Consequently, up.time provides the option whether you want scheduled maintenance to count against your SLA. Notice I said scheduled maintenance and not ad-hoc maintenance. Ad-hoc maintenance is something that’s not planned, which means customers will experience unplanned outage and should be counted against the SLA. Whether it’s scheduled or ad-hoc maintenance, you can count on up.time to accurately measure your SLA.
Most people don’t think about how maintenance could affect monitoring and SLA reporting in their IT environment. Make sure you don’t get caught in the cold. Take control over how you manage your IT infrastructure. Download up.time’s 30 day free trial and see the difference!
