I love that it's free, but more importantly - easy to use! It does what we need for our needs (monitoring of websites) without being too intrusive or complicated. The only thing which could be improved is if you were able to filter certain parts of your site from being monitored by alertbot so as not have all errors show up in one dashboard at once. We are solving problems with downtime issues caused by poor server maintenance / lack thereof. Our hosting provider has been doing this very well until recently when they started getting complaints about slow speeds due to high load times. This was causing us some serious losses. With alerts bot, now everything works perfectly again. Thanks guys :)! No worries anymore! You can monitor uptime using Alert Bot and notify me via email anytime there is an issue found during my absence so i don't miss any important notices.
