At present, the syslog-ng (syslog-ng Open Source Edition) does not support to set the hostname of the server in the configuration. syslog-ng uses DNS system to resolve the system name or if it is explicitly switch off (with couple of options) it will use the IP. Sometimes the DNS name of the system may be not valid, for example in containers, or just for better naming purposes it is useful to have just a simple option to set the system’s hostname in the syslog packets.
The easiest and best way to change the system’s hostname in the packets is to use substitution rules with rewrite. In fact, the rewrite rule may operate on soft parts of the macros like MESSAGE, PROGRAM, HOST or user defined macros. The syslog message format and its “fields” could be seen in the RFC5424. It’s worth adding it is possible to replace the whole macro or just part of it.
Here is the configuration to set the system’s hostname:
#substitution rule
rewrite my_host { set("my-server-name", value("HOST")); };
#use the rule before the destination!!!
log { source(src); rewrite(my_host); destination(messages);};
The substitution rule should be used before the destination rule to take effect.
Here is a more complex example to set the system’s hostname only to certain packets: Keep on reading!
The basic topics to manage a Groestlcoin wallet with the official software (ALWAYS use only official software) are:
Groestlcoin Core provides two key functionalities – become a Groestlcoin node, i.e. a part of the Groestlcoin network and the Groestlcoin wallet with command line interface and graphical user interface.
Groestlcoin Core can generate and Groestlcoin address.
a Groestlcoin wallet contains Groestlcoin addresses.
the Groestlcoin Core has a wallet functionality application, but before using it the wallet needs to synchronize with the Groestlcoin network. So the Groestlcoin GUI application will start a Groeslcoin node and it will try synchronizing with the network.
Groestlcoin Core includes groestlcoin-qt application, which offers the graphical user interface
Using groestlcoin-qt is really simple to manage wallets, generate Groestlcoin addresses, and get information for the local Groestlcoin node, which is used by the wallet application.
Here are the steps needed to transfer funds under the Linux distro of Ubuntu securely, but this time from the Gnome. To be able to transfer money securely without any 3rd party involved (no online wallet or wallets, which is unclear which node they connect to) just funds from your personal Groestlcoin wallet address on your computer to another Groestlcoin wallet address it is needed a running Groestlcoin node using Groestlcoin Core graphical user interface:groestlcoin-qt – this application provides basic graphical user interface for managing the Groestlcoin wallets. After the Groestlcoin Core is build and installed (check this article – Build and run the Groestlcoin Core 25.0 node with a graphical wallet), start the /[user_home_directory]/groestlcoin-core/bin/groestlcoin-qt. Apparently, the Groestlcoin site offers a compiled version of Groestlcoin Core (with an installer for Windows, too), but be careful what you download and from where! The best way is to just follow our article to build it yourself under Ubuntu.
More on the Groestlcoin topic – https://ahelpme.com/tag/groestlcoin/.
SCREENSHOT 1) The loading screen at the start of groestlcoin-qt application.
It may take time to start because it is loading the local cached block index and if the node was fully synced lately, it may take a minute or two to load.
the Groestlcoin wallet application (i.e. Groestlcoin node, it is the same application) needs a synchronized Groestlcoin to operate properly, such as send and receive Groestlcoin coins.
the Groestlcoin wallet may be created, loaded or imported with the Groestlcoin tools.
if there is only one Groestlcoin wallet loaded it would be the default one and it would not require additional options to the Groestlcoin tool to specify, which wallet would be used for the current command.
Here are the steps needed to transfer funds under the Linux distro of Ubuntu securely. To be able to transfer money securely without any 3rd party involved (no online wallet or wallets, which is unclear which node they connect to) just funds from your personal Groestlcoin wallet address on your computer to another Groestlcoin wallet address it is needed a running Groestlcoin node using Groestlcoin Core command line tool:groestlcoin-cli – this is command line tool for managing the Groestlcoin wallets.
STEP 1) Install and run a Groestlcoin node with groestlcoind
The first step is to start a Groestlcoin node by following this updated article – Building from source and run a Groestlcoin node (cli only) under Ubuntu 22.04 LTS. It will help the user to build from the official source code the Groestlcoin Core software, which will include the Groestlcoin node and wallet functionalities. All of the file paths and application names are real and correct if the above article was used.
It’s worth mentioning, that the Groestlcoin node must be running and synced with the Groestlcoin network. Here is how to check it:
In continuation to the article Building from source and run a Groestlcoin node (cli only) under Ubuntu 22.04 LTS, which offers only a command line management to the Groestlcoin wallets, this article will show a more convenient way with a graphical user interface. Groistlcoin Core software includes a graphical user interface for the Groestlcoin wallet.
The first thing is to build the Groestlcoin Core software as shown in the link above with some additional dependencies and options.
It’s worth noting there is a package for the graphical Groestlcoin wallet on the official site of Groestlcoin, but the idea behind this series of articles is to build everything from the official source code and to run an own Groestlcoin node, which will be used for the user’s Groestlcoin wallet. Such no trusting anyone or any site, but only the official source code of the project. The security is really important in the crypto world.
Here are the steps to build and run the Groestlcoin node with wallet functionality – command line and graphical user interface. The graphical user interface uses QT5 to build the wallet interface and all libraries are included in the official Ubuntu repositories.
First, install the dependencies but with additional libraries including the QT5 and qrencode. Update the system and install the needed additional binaries and libraries to build and run the Groestlcoin core package. These dependencies include the ones needed to build the Groestcoin wallet functionality with GUI! By default, many Linux systems won’t even include dependencies needed to build the wallet.
When trying to read the MariaDBbinlog files, the reading may be interrupted with an error message, and the reading will stop:
ERROR: Found out of order GTID. Got 0-3-855835750755 after 0-1-855835750756
Some positions are shown but after 24 lines of 1236849 file, the mariadb-binlog / mysqlbinlog program interrupts with an error.
It turns out the problem is that the mariadb-binlog / mysqlbinlog reads the binlog files with GTID strict mode, because it is enabled by default! But the servers may have turned it off, so the binlog files are in the wrong format for the strict mode reading. The mode to read the binlog files should be the same as the MySQL / MariaDB server mode that created the binlog files.

The generation of a new Groestlcoin address is relatively simple, just use the command line tool – groestlcoin-cli, which is a Groestlcoin Core RPC client talking to the Groestlcoin node. So a working and synchronized Groestlcoin node is needed. Check out Building from source and run a Groestlcoin node (cli only) under Ubuntu 22.04 LTS for more information how to build and run a Groestlcoin node.
DO NOT TRUST any online website or any other Internet source to generate your Groestlcoin wallet address for you. DO IT YOURSELF with the official software from the official site!
If the user followed the above link to build and run a Groestlcoin and has waited to synchronize, it is time to use the groestlcoin-cli to create a wallet and then generate addresses. In fact, the wallet contains Groestlcoin addresses and it may be encrypted for better security. The Groestlcoin node is running and synchronized.
STEP 1) Create a new or load an old Groestlcoin wallet.
There is no default wallet and no wallet is loaded automatically on start, by default (indeed a wallet may be automatically loaded, but it should be specified on loading).
List all the Groestlcoin wallets under the current user:
myuser@mydesktop:~$ cd groestlcoin-core/bin/
myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli listwallets
[
]
myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli listwalletdir
{
"wallets": [
]
}
myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli listaddressgroupings
error code: -18
error message:
No wallet is loaded. Load a wallet using loadwallet or create a new one with createwallet. (Note: A default wallet is no longer automatically created)
Apparently, there are no wallets, so here is how to create a wallet:
Create a wallet with:
myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli createwallet my-groestlcoin-wallet
{
"name": "my-groestlcoin-wallet"
}
myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli encryptwallet 'joo8laeW9Chietae&phu'
wallet encrypted; The keypool has been flushed and a new HD seed was generated (if you are using HD). You need to make a new backup.
When creating one wallet, it will become the default one, and all commands on groestlcoin-cli will use it. To specify exactly the name of the wallet with the command, the option “-rpcwallet=” should be used. In general, with one wallet there is no need to specify the wallet name, but when there are two or more loaded wallets, it is mandatory to specify with “-rpcwallet=” the wallet name.
Creating one more wallet with groestlcoin-cli will result in two loaded wallets, so after that, all commands should include “-rpcwallet=”.
myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli createwallet my-groestlcoin-wallet-2
{
"name": "my-groestlcoin-wallet-2"
}
myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli -rpcwallet="my-groestlcoin-wallet-2" encryptwallet "ief0ahshao8ca8Dai-ng"
wallet encrypted; The keypool has been flushed and a new HD seed was generated (if you are using HD). You need to make a new backup.

It was a bit while after the Building from source a Groestlcoin node (cli only) under Ubuntu 16 LTS. So after 6 years is it the same procedure or there are additional or simplified steps (to build) and run a cryptocurrencyGroestlcoin node? The GRS price seems the same as it was 6 years ago, but there are some new things in the software.
The first step is to build the software and it is one of the most important steps – download the source code ONLY from the official source, check the official site https://www.groestlcoin.org/groestlcoin-core-wallet/ where the source code could be downloaded or to see where is the official place for the source code – https://github.com/Groestlcoin/groestlcoin. Check the links yourself! The https://github.com/Groestlcoin/groestlcoin git link will be used to download the latest stable version of the code and to build a Groestlcoin node, which may or may not include wallet capabilities. Building the Groestlcoin core package from the source you’ll have your private and secure Groestlcoin node (and wallet), which could be used to make secure transactions and receive funds in the Groestlcoin network and a lot more! DO IT YOURSELF – the most secure way of generating a Groestlcoin wallet address, making transactions such as sending and receiving coins, and storing your wallets.
STEP 1) Update your system and install dependencies
Update your system and install the needed additional binaries and libraries to build and run the Groestlcoin core package. These dependencies include the ones needed to build the Groestcoin wallet functionality! By default, many Linux systems won’t include dependencies needed to build the wallet.
This article is a follow up after the Run podman/docker InfluxDB 1.8 container to collect statistics from collectd, where the time series database InfluxDB stores data and by using Grafana in another container it is easy and lightweight enough to visualize the collected data.
Containerizing the Grafana service is simple enough with docker/podman, but there are several tips and steps to consider before doing it. These steps will significantly ease the maintainer’s life, making upgrading, moving to another server, or backup important data really easy – just stop and start another container with the same options except name and container version.
Here are the important points to mind when running Grafana 9 in a docker/podman container: Keep on reading!
This article shows how to make a graph showing a Linux machine’s CPU frequency changes. This plugin gathers CPU Frequency of all the virtual processors aka cores. In general, this module collects simple data for the processors’ frequencies like the Linux command of showing the number in /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq. The purpose of this article is to make a graph showing CPU frequency changes, which may be a hit for CPU load on the system.
to enable the CPUFreq plugin, load the plugin with the load directive in /etc/collectd.conf
LoadPlugin cpufreq
The CPUFreq plugin collects data every 10 seconds.
cpufreq_value – a single Gauge value – a metric, which value that can go up and down. It is used to store the current CPU (or core)frequency. So there are multiple gauge values with different tags for the different cores (processors).
tag key
tag value
description
host
server hostname
The name of the source this measurement was recorded.
type
cpufreq
The current frequency of the current processor or the current core.
instance
processors/cores ids
The processors (or cores) starting from 0 to N.
A Gauge value – a metric, which value that can go up and down. More on the topic – Data sources.
A GAUGE value is simply stored as-is. This is the right choice for values which may increase as well as decrease, such as temperatures or the amount of memory used, frequencies, etc.
To cross-check the value, the user can use the /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq and replacing the * with integer number like 0, 1, 2, etc.
