Ubuntu Linux Crisis & General Troubleshooting Tools
Summary
Thought I’d put together a list of Linux tools based on different criterias. The idea for this came from Brendan Gregg who just published a post; which is in the Reference, related to installing certain tools preferably before an outage occurs. I will utilize much of that list for this one.
This post is specifically geared toward Ubuntu Server and will be updated regularly as time goes on. Included will be the command used to install the packages listed in this.

| procps | ps(1), vmstat(8), uptime(1), top(1) | basic stats |
| util-linux | dmesg(1), lsblk(1), lscpu(1) | system log, device info |
| sysstat | iostat(1), mpstat(1), pidstat(1), sar(1) | device stats |

Install
Command for installing these packages on Ubuntu. Some come with Ubuntu Server by default and some dont. This just makes sure they are and takes away any guess work there may be related to how Ubuntu handles their default packages.
apt-get -y install procps util-linux sysstat tcpdump \
nicstat ethtool iproute2 curl cpuid
