阅读更多关于 Administration and Monitoring of Apache-Camel routes in ServiceMix

问题 Being a user of Camel and ServiceMix I frequently need to monitor those tools for development purposes. I mainly use JConsole to access MBeans from ServiceMix and Camel. It gives a few really helpful metrics for an ESB developer. I also use karaf (web)console to track my route and bundles status. Looking around StackOverflow I found an interesting link that explains how to setup Hyperic HQ for ServiceMix 4: Monitoring Servicemix with Hyperic HQ. Are they other tools you would consider worthy

阅读更多关于 How to use proximity sensor programmatically with iOS development?

问题 After some googling, I can understand that the "proximity sensor" which is used to on/off screen when the device is away/near from the user. I watched this video (watch from 30th sec) and surprised about this cool stuff. I want to implement it in my app. But I come to know that there is no public API is available that can protect the screen lock when proximityMonitoringEnabled is YES . Then how can the above app did this? For clear understanding, I'm copying some code. Enable the proximity

How do I enable snmp on CoreOS

阅读更多关于 How do I enable snmp on CoreOS

I cannot seem to find any useful info on the topic. Furthermore, what is the best way to monitor CoreOS (we use observium). If standard Linux SNMP metrics are most you need, you just want to deploy a container that runs SNMP daemon. For that purpose you will probably need to expose it to host's network namespace ( --net=host , if you are using Docker) and then you definitely need to bind-mount /proc (with -v /proc:/hostproc passed to docker run ). The only unusual thing you would need point the SNMP daemon at is the /hostproc instead of /proc . You can probably try using the polinux/snmpd

How can I monitor / limit network traffic used by my app?

阅读更多关于 How can I monitor / limit network traffic used by my app?

I would like to be able to measure network traffic and limit it. I'm looking for something that lets me know between two calls how much data has been sent and received. Also, I would like to be able to limit network traffic (in & out) for my app. Something like the NetLimiter software (great app!) but which I can control from my code. Do you know some third party components to do this ? This is meant to be used on a datasnap 2009 thin-client. If you use Indy, then use the TIdInterceptThrottler class. Simply set the BitsPerSec property. My understanding is that DataSnap is based on Indy. If you

Automatically restarting HHVM when it stops responding but process not dead

阅读更多关于 Automatically restarting HHVM when it stops responding but process not dead

I'm having a problem where every 12-24 hours, HHVM crashes but it seems to leave the process running. It seems most providers just use php5-fpm as a failover within nginx for stability. However, this won't restart the non-responsive hhvm instance. Since the process is left running, most server monitoring solutions will see it as a live daemon, and not restart it. HTTP monitoring can be slow to react. Is it possible to trigger the hhvm restart on failover? If not, what would be the best solution to ensure a listening daemon that's non responsive is restarted. kristapsk posted a solution on

Observing or monitoring users working with an application remotely

阅读更多关于 Observing or monitoring users working with an application remotely

问题 I'm a believer in observing what users are doing with an application. I think that it is the only way to get an accurate picture of what people are doing. However, I don't always want to be sitting with them and peering over their shoulder; apart from the time burden it is a distracting for them and may also change their behaviour. What I'd really like is a way of observing/recording/monitoring/logging what users are doing in a windows form application. I'd also like to be able to analyse the
