Docker is a very cool tool to manage Linux Containers.
Interesting podcast about monitoring in near-realtime and the faults of threshold-based monitoring
OpenTSDB is a distributed, scalable Time Series Database (TSDB) written on top of HBase. OpenTSDB was written to address a common need: store, index and serve metrics collected from computer systems (network gear, operating systems, applications) at a large scale, and make this data easily accessible and graphable.
On one of the servers I manage we needed to load ipmi modules for hardware checks.
To load the required modules during the boot, we need to create a new file in /etc/sysconfig/modules/, I called it ipmi.modules. The file is a common shell script and it contains only a few lines:
#!/bin/bash if [ ! -c /dev/ipmi0 ]; then modprobe ipmi_devintf fi modprobe ipmi_si exit 0
Make sure the file is executable:
chmod +x /etc/sysconfig/modules/ipmi.modules
As usual, for more info check the official documentation from Red Hat.
I installed CyanogenMod on my tablet to get better performances from it.
