Before all thanks for your kind and quick reply! Ok all your answers are quite clear. Just some other question:
A) Scheduled downtime: In nagios the main advantage of "scheduled downtime" (or maintenance windows as you prefer to define it...the concept is the same) is NON ONLY the ability to turnoff emails but, above all, the ability to have detailed statistics. I mean: if you have a customer that needs to know the uptime, you can create a report and, supposing it shows 98% of uptime and 2% of downtime, the customer could say to you (as alread happened to me!): hey guy could you explain to me because uptime is not 100%?! And I kindly replied: the 2% of dowtime really is distinguished between 1,90% of "schedule dowtime" (patches applied to servers, hardware maintenance etcc...). and 0,10 of real problems. So...your uptime is quite perfect! This is the nagios's default and I think it is an excellent way! :) B) Recurring scheduled dowtime: This is a future that nagios doesn't provide out of the box but in the nagios's faq there is a workaround that, to sum up, consists in a cron job. http://www.nagios.org/faqs/viewfaq.php?faq_id=80&expand=false&showdesc=false This can be useful when you know that some servers (tipically windows) are rebooted every weeks or every months. The ability to configure a "recurring scheduled downtime" is useful because you don't have to manual configure it every week and uptime's statistichs won't be affected. C) Samba and encryption protocol So..Zenoss use samba! This is a great way to work my best compliment to Zenoss team! I have only a question about this topic: In a windows 2003 Active Directory, isn't kerberos the default protocol? I always thought that when you login to your domain or when you configure a windows service with a specific domain user (in my case nrpe_nt), you use KERBEROS and not ntlm. I know this is not a Zenoss questions so...I only ask you a shor reply about this. D) Webinject,Nagvis and network whatermap - Webinject Webinject is a web application test tool. To sum up you can simulate an entiere transaction. One example: to simulate the login to your webmail and check for new mail. It is a nagios plugins already integrated in groudnwork that autocamically creates rrd files. Anyway I just founded that Zenoss provide ZenWebTX: http://www.zenoss.com/community/docs/howtos/monitoring-websites-with-httpmonitor. It explain at the end of the page: In addition to the HttpMonitor Core ZenPack, there is another ZenPack related to web monitoring available for Enterprise customers: ZenWebTX. ZenWebTx extends Zenoss' web monitoring capabilities beyond the simple uptime, load time, and size checks available in the Core version. With ZenWebTx you can have Zenoss navigate through your entire web application checking for compliance at each step. Multiple timers can be set along the way to measure response time for each operation of the synthetic transaction as well as the total time for the entire transaction to complete. So..I replied by myself b) Nagvis is a tool that enable you to import visio (but not only) files and to have red or gree on this "map". Very useful to identy where the problem is physically on. I think Zenoss doesn't incluede it d) Network whatermap is a great tool that enable to have a graphical and realtime rappresentation of your bandwith usage and workflow. Have a look to him it is very impressive. I think Zenoss doesn't include it. So..at the end I'll expose my personal considerations about "groundwork vs zenoss". Please tell me what you think about it: Before all I think that in order to give a final sentence you need to know both products. Anyway my opinion is: Zenoss commercial version is much more expensive than Groundwork commercial version but it is definitively superior because provides more and more "out of the box plugins" (example: websphere doesn't exist for groundwork and I need it) and the user's interface is much more nice and user friendly. Zenoss core is much more castrated than groundwork (above all speaking about wmi that I tested with Zenoss and groundwork both) so..if your businnes doesn't require commercial version Groundowrk is better otherwise Zenoss could be a better choise. Anyway both ot them are great products! Please tell me your opinion! -------------------- m2f -------------------- Read this topic online here: http://forums.zenoss.com/viewtopic.php?p=32729#32729 -------------------- m2f -------------------- _______________________________________________ zenoss-users mailing list [email protected] http://lists.zenoss.org/mailman/listinfo/zenoss-users
