Having trouble? Here are solutions to common problems you might encounter while using Reporting.
Reporting launches a "headless" web browser called Chromium on the Kibana server. It is a custom build made by Elastic of an open source project, and it is intended to have minimal dependencies on OS libraries. However, the Kibana server OS might still require additional dependencies for Chromium.
Make sure Kibana server OS has the appropriate packages installed for the distribution.
If you are using CentOS/RHEL systems, install the following packages:
If you are using Ubuntu/Debian systems, install the following packages:
Text is rendered incorrectly in generated reportsedit
If a report label is rendered as an empty rectangle, no system fonts are available. Install at least one font package on the system.
If the report is missing certain Chinese, Japanese or Korean characters, ensure that a system font with those characters is installed.
Missing data in PDF report of data table visualizationedit
There is currently a known limitation with the Data Table visualization that only the first page of data rows, which are the only data visible on the screen, are shown in PDF reports.
Ensure that the
headless_shell binary located in your Kibana data directory is owned by the user who is running Kibana, that the
user has the execute permission, and if applicable, that the filesystem is mounted with the
The Chromium binary is located in the Kibana installation directory as
data/headless_shell-OS_TYPE/headless_shell. The full path is logged
the first time Kibana starts when verbose logging is enabled.
Whenever possible, a Reporting error message tries to be as self-explanatory as possible. Here are some error messages you might encounter, along with the solution.
"Max attempts reached"edit
There are two primary causes of this error:
- You’re creating a PDF of a visualization or dashboard that spans a large amount of data and Kibana is hitting the
- Kibana is hosted behind a reverse-proxy, and the Kibana server settings are not configured correctly
Create a Markdown visualization and then create a PDF report. If this succeeds, increase the
xpack.reporting.queue.timeout setting. If the
PDF report fails with "Max attempts reached," check your Kibana server settings.
"You must install nss for Reporting to work"edit
Reporting using the Chromium browser relies on the Network Security Service libraries (NSS). Install the appropriate nss package for your distribution.
"Unable to use Chromium sandbox"edit
Chromium uses sandboxing techniques that are built on top of operating system primitives. The Linux sandbox depends on user namespaces, which were introduced with the 3.8 Linux kernel. However, many distributions don’t have user namespaces enabled by default, or they require the CAP_SYS_ADMIN capability.
Elastic recommends that you research the feasibility of enabling unprivileged user namespaces before disabling the sandbox. An exception is if you are running Kibana in Docker because the container runs in a user namespace with the built-in seccomp/bpf filters.
Kibana server logs have a lot of useful information for troubleshooting and understanding how things work. If you’re having any issues at
all, the full logs from Reporting will be the first place to look. In
