rsyslog has "great" latency when writing to local log file

Asked 2021-Dec-21 at 15:43

I'm using rsyslog to write logs on a Raspberry Pi, with a standard /etc/rsyslog.conf file. Im writing logs from Bash scripts using the logger command and from Python scripts using the syslog library.

Bash Example:

ANSWER

Answered 2021-Dec-21 at 15:43

For anyone interested... I managed to solve the issue.

Observation

The problem didn't lie with the python syslog library and neither with the bash logger command.

Rsyslog gathers log messages and adds them to the main queue. A worker thread then pulls messages off the main queue and delivers them to their desinations and/or adds the message to an action queue. If a worker is unable to deliver messages to a destination, all progress of that queue will block until that delivery is able to succeed (or hits the retry limit and permanently fails).

So the message wasn't written for a few minutes or got entirely "deleted", because rsyslog tried to establish a connection with a server that wasn't responding.

The Solution

This is a snippet of my /etc/rsyslog.conf before:

Using a userspace driver in Linux daemon

I've found a userspace driver (https://github.com/rahlskog/VM167) and have set some /etc/udev rules and ldconfig paths so that I can run the test and it works as expected.

You can use the below to set the variable without outputting to console.

$openlog = $openlog -eq "YES" ? "NO" : "YES"

I do not yet know why your example outputs to the console. I went through the implementation and this was a use case that was never handled and isn't handled during testing.

SQL Insert in Java class throws error on the SQL Statement

Asked 2021-Aug-24 at 17:33

I keep getting an error on my statement when running the postmethod of my servlet. However, when I simply try to do it in the database directly it works just fine.

I'm using a tomcat 9 server; and postgres database. Java Openlogic 11;

The message I'm getting is: ERROR: column "doe" does not exist Position: 61 Which refers to the value I'm trying to insert.

What am I missing here? I'm still learning so any and all information is very welcome. Thanks in advance.

...

ANSWER

Answered 2021-Aug-24 at 17:33

Your query seems to be fine, so it must be a problem with the database you're trying to insert. Can you specify the schema you're trying to do the insert on? For example: "INSERT INTO test.testinserts (lastname, firstname, city) VALUES ("+ lastname + "," + firstname + "," + location + ");"

Also, check your DB connection. For example, try to manually insert some data and then query it from your code.

Edit: As said in other posts, this was made to check the example exposed. You should build querys doing VALUES (?, ?, ?) and then use stm.setString(1, lastname), stm.setString(2, firstname), etc to avoid SQL injection.

Terraform Azure 2xLinux VM with httpd + LoadBalancer not working

Asked 2021-Aug-09 at 08:07

I am trying to create a Terraform PoC that has two centos VMs and an Azure Load Balancer.
Each VM has one private and one public IP and installed the httpd package.
Even the elements are provisioned successful, accessing the Public IP of the Load Balancer does not return the default httpd content (inside the CentOS VM curl localhost or the IP returns the correct content). No firewall enabled on CentOS.
Below it the Terraform file. (Location i am using is westeurope).

Q: What am I missing in the configuration for the Load Balancer? All items are provisioned, no error from terraform, when accessing the public ip of the load balancer I get time out instead of the default apache page.

ANSWER

Answered 2021-Aug-09 at 08:07

Based on the comments.

The issue was caused by not opening port 80 in azurerm_network_security_group.test. Only port 22 was allowed. Thus opening port 80 solved the issue.

ANSWER

Answered 2021-May-18 at 06:28

The short answer is that the availability set and the availability zone can't exist at the same time. You can take deeper learning about them. The former is in a logical grouping of the VMs and the latter improves the availability on the physical regions.
