Setting up the monitoring on all of your devices may seem daunting, but auto-discovery makes it simple. There is no need to know what objects on a device to monitor, or even how to configure them. All you need to know is the hostname or IP address, and Active Discovery does the identification and configuration. Some of the items that it looks for on each device include:
- Interfaces
- Volumes
- Physical disks
- Temperature sensors
- Virtual IPs
- VPN links
- DSU/CSUs
- Applications

Simple sinatra based dashboard for redis. After seeing the fnordmetric project I was inspired to write this. Some of the ideas there have be carried over here.

I often find myself wondering how our redis instances are being used and which areas of the application are the heavy consumers. It’s also useful to predict how the memory consumption is growing over a period of time. Luckily, redis offers a couple of commands, INFO and MONITOR that expose some useful bits of information. Using the data from these two commands, it’s easy to build up a trend over a period of time.

redis-stat is a simple Redis monitoring tool written in Ruby.
It is based on INFO command of Redis, and thus generally won’t affect the performance of the Redis instance unlike the other monitoring tools based on MONITOR command.
redis-stat allows you to monitor Redis instances
either with vmstat-like output from the terminal
or with the dashboard page served by its embedded web server.

– too much IO stats? IO is important!, if we are serving thousands of files per hour.

I’m setting up a new machine with 8cores and 8Gb of RAM.
I had to choose between Ubuntu 32bits or 64bits…
Ubuntu 64bits was the choice. Why?
If you have more than 4 GB of RAM go for 64 bit else 32 bit is just fine.
Use 64bit in case you do
- video editing and processing
- sound editing and processing
- graphic editing and processing
- work with large files (e.g. databases, large log files,…)

Backup a folder
tar -cvpzf /BackupDirectory/backupfilename.tar.gz /ImportantData/directory/path
c = Create
v = Verbose mode
p = Preserving Files and Directory Permissions.
z = This will tell tar that compress the files further to reduce the size of tar file.
f = It is allows to tar get file name.

I’v deployed a work on one of my clients – a french one – server and even using charset=”UTF-8″ meta in HTML, some characters were displayed different from what they should.
cópia was showed coÌpia
I had to add the following line to .htaccess – forcing the Charset to be UTF-8
AddDefaultCharset UTF-8
or
AddDefaultCharset Off
disabling Default Charset! 🙂

NAXSI is Nginx Anti XSS & SQL injection. In simple words, it’s a firewall for web applications (WAF) for Nginx, protecting from XSS, SQL injections, CSRF, Local & Remote file inclusions. NAXSI is known for its fast working and simple configuring. It’s a good alternative for mod_security in Apache.
What would you need NAXSI for?
It’s obvious that’s the best way of protection from attacks is correctly written code, but in some situations WAF and particularly NAXSI can help:
- low quality of site code with no resources or possibilities of rewriting it;
- closed source code in which fixing mistakes is impossible;
- the quality of code is unknown and unpredictable (i.e. shared hosting).
