* docs: comprehensive audit, Spine poller overhaul, and technical refactor - Overhaul Spine documentation (Spine.md) with complete end-to-end guide: architecture, prerequisites for modern distros (EL8/9 CRB, Ubuntu 22/24, Debian 11/12, FreeBSD), SUID root permissions, secure spine.conf setup (0640), Web UI configuration (Paths, Poller type, Data Collectors tuning), MySQL max_connections sizing, and troubleshooting. - Fix broken links and anchors (Hardening, SNMP data queries, Hook API references). - Fix broken image reference in Sites.md (add-site.JPG -> add-site.png). - Fix syntax errors in documentation PHP code blocks, including invalid parenthesization, missing SQL execute quotes, and malformed comments in FAQ. - Fix DevOps installation commands: use config.php.dist, correct systemctl service names for MySQL/MariaDB/PHP-FPM, remove nonexistent php-json, add missing composer install, and correct Debian/Ubuntu systemd environment path. - Correct grammatical errors, repeated words, and typos across all markdown documents. - Remove obsolete unreferenced duplicate installation guides. Signed-off-by: Thomas Vincent <thomasvincent@gmail.com> * docs: correct reviewed examples and guidance Signed-off-by: Thomas Vincent <thomasvincent@gmail.com> * docs: correct guidance that disagrees with the Cacti source Verified each claim against include/global_arrays.php, lib/auth.php, lib/functions.php, host_templates.php and the Spine config parser. The notable ones: api_plugin_safe_exec() does not exist on either branch, Spine reads DB_Pass rather than DB_Password, and the CDEF special data source table was missing five entries and renamed four others. Signed-off-by: Thomas Vincent <thomasvincent@gmail.com> * docs: wrap Spine prose and fence the connection sizing formula The formula's bare asterisks rendered as emphasis, dropping the multiplication signs. Signed-off-by: Thomas Vincent <thomasvincent@gmail.com> * chore: refresh copyright year in scripts and issue templates Signed-off-by: Thomas Vincent <thomasvincent@gmail.com> --------- Signed-off-by: Thomas Vincent <thomasvincent@gmail.com>

# GPRINT Presets
|
|
|
|
GPRINT Presets are an object in Cacti used for formatting Legend output on
|
|
RRDtool Graphs. These GPRINT Presets closely follow printf(), sprintf() ANSI
|
|
syntax. They are simple to create and edit. You can find the format strings on
|
|
the [RRDtool Website](https://oss.oetiker.ch/rrdtool/doc/rrdgraph_graph.en.html#PRINT).
|
|
|
|
The stock GPRINT Presets are generally sufficient for most **Graph Templates**,
|
|
but they can easily be extended, and are a part of the Graph Template Export XML
|
|
file. So, they are portable once created.
|
|
|
|
In the image below, you can see the default GPRINT Presets and the actions that
|
|
can be taken on them. Keep in mind that once a GPRINT Preset is being used by a
|
|
**Graph** or a **Graph Template**, it cannot be removed.
|
|
|
|
|
|
|
|
Below you can see the GPRINT Preset edit screen.
