Domino products offer a wealth of statistical data that play a crucial role in predicting and preventing issues in production environments. As a mature product, Domino has been delivering these valuable insights for many years, helping to maintain high-quality service for clients.
What Do These Statistics Tell Us?
Looking at the code 200 histogram, we see that 96% of requests are fulfilled in under 2 seconds, with the majority processed in under 1 second. But what does this mean for our server's current state?
Without knowing the uptime—whether it's been 10 minutes or 2 weeks—this data is limited.
High response times could have occurred just now, or they might be skewed by a user with slow internet in a remote location week ago.
How Do We Know if the Server is Healthy Right Now?
Simply waiting and watching isn’t effective. We need a “wait and compare” approach. For example, in the image, only the 000-001 statistic has increased, giving us confidence that response times are stable. However, manually checking for changes isn’t practical.
This is Where CYMON from CYONE Steps In!
CYMON www.cyone.eu/cymon simplifies monitoring by automatically calculating deltas over time, showing trends without the need for manual comparison. This dynamic view of server health makes it easy to spot issues immediately.
CYMON monitoring has also alerting on SMS, Telegram, email or even MS Teams(Forgive me). Based on Zabbix www.zabbix.com CYMON can be installed under <5 min. Providing valuable insights immediately.
Isn’t that great? There are more than 1000 important statistics checked in realtime, calculating right values for you. CYMON can monitor also NSF applications, View Open Times,
This one histogram is top of the iceberg. It is important to monitor also histogram how quickly Traveler connects to Mail server. To Database where all subscriptions are stored. Also
Do I need to defragment my Database (Derby). If you are in HADR mode, then it is even more interesting.
For example MySQL be default has only 151 Connections that are allowed. If you run 8 or more HTMO/Traveler servers you will hit this limit.
In CYMON we see immediately how quickly we can connect to MySQL (1), how much time it takes to lookup users subscribed folders/last sync times (2). On PieChart 2 we see 100% is done under 1 second.
This will tell you instantly if RDBMS is a bottle neck. No it is not, all times are perfect. Of course now we see nice picture, while CYMON will highlight you dirty place and make your Domino SHINE!
Everything synchronised under 1 second. We also see (2) instruction what to do if Bad buckets will grow (like 005-10, or slowed buckets).
And finally we see also what type of problem we got so far during server uptime(3).
If you find this interesting in more please comment, I have a lot of cool stuff about Traveler and Domino monitoring as such.
P.S. Thank you Martin from (http://www.sidra400.com), fixed CSS, it is better now.
