Efficiently find specific information in Tomcat logs
This article introduces several methods to quickly locate specific information in Tomcat logs to help you quickly troubleshoot problems.
Method 1: Command line tool
First, find the Tomcat log file, which is usually located in the logs
folder under the Tomcat installation directory.
View logs: Use the
cat
command to view the content of the log file, for example:cat /path/to/tomcat/logs/catalina.out
. (Please replace/path/to/tomcat/
with your Tomcat installation path)Filter information: Use the
grep
command to filter specific keywords. For example, find a log line containing "Error":grep "錯(cuò)誤" /path/to/tomcat/logs/catalina.out
.
Method 2: Text Editor
Open the log file directly and use the text editor's search function (usually Ctrl F or Cmd F) to enter keywords to search.
Method 3: Log Analysis Tool
For large log files or require more advanced analysis, it is recommended to use professional log analysis tools such as ELK Stack (Elasticsearch, Logstash, Kibana) or Splunk. These tools provide powerful search, filtering, and visualization capabilities.
Method 4: Adjust log level
Modify Tomcat's logging.properties
file, adjust the log level (such as DEBUG, INFO, WARN, ERROR), control the number of log information recorded, and reduce unnecessary information interference.
Method 5: Log segmentation
In order to facilitate the management of large log files, you can use tools such as cronolog
to split log files by date to facilitate the search of logs for specific time periods.
With the above methods, you can efficiently extract the required information from the Tomcat logs, quickly diagnose and resolve problems.

Ordinary investors can discover potential tokens by tracking "smart money", which are high-profit addresses, and paying attention to their trends can provide leading indicators. 1. Use tools such as Nansen and Arkham Intelligence to analyze the data on the chain to view the buying and holdings of smart money; 2. Use Dune Analytics to obtain community-created dashboards to monitor the flow of funds; 3. Follow platforms such as Lookonchain to obtain real-time intelligence. Recently, Cangming Money is planning to re-polize LRT track, DePIN project, modular ecosystem and RWA protocol. For example, a certain LRT protocol has obtained a large amount of early deposits, a certain DePIN project has been accumulated continuously, a certain game public chain has been supported by the industry treasury, and a certain RWA protocol has attracted institutions to enter.

The duration of the airdrop dividend is uncertain, but the LayerZero, StarkNet and ZK ecosystems still have long-term value. 1. LayerZero achieves cross-chain interoperability through lightweight protocols; 2. StarkNet provides efficient and low-cost Ethereum L2 expansion solutions based on ZK-STARKs technology; 3. ZK ecosystem (such as zkSync, Scroll, etc.) expands the application of zero-knowledge proof in scaling and privacy protection; 4. Participation methods include the use of bridging tools, interactive DApps, participating test networks, pledged assets, etc., aiming to experience the next generation of blockchain infrastructure in advance and strive for potential airdrop opportunities.

The coordinated rise of Bitcoin, Chainlink and RWA marks the shift toward institutional narrative dominance in the crypto market. Bitcoin, as a macro hedging asset allocated by institutions, provides a stable foundation for the market; Chainlink has become a key bridge connecting the reality and the digital world through oracle and cross-chain technology; RWA provides a compliance path for traditional capital entry. The three jointly built a complete logical closed loop of institutional entry: 1) allocate BTC to stabilize the balance sheet; 2) expand on-chain asset management through RWA; 3) rely on Chainlink to build underlying infrastructure, indicating that the market has entered a new stage driven by real demand.

The most popular tracks for new funds currently include re-staking ecosystems, integration of AI and Crypto, revival of the Bitcoin ecosystem and DePIN. 1) The re-staking protocol represented by EigenLayer improves capital efficiency and absorbs a large amount of long-term capital; 2) The combination of AI and blockchain has spawned decentralized computing power and data projects such as Render, Akash, Fetch.ai, etc.; 3) The Bitcoin ecosystem expands application scenarios through Ordinals, BRC-20 and Runes protocols to activate silent funds; 4) DePIN builds a realistic infrastructure through token incentives to attract the attention of industrial capital.

In the ever-changing virtual currency market, timely and accurate market data is crucial. The free market website provides investors with a convenient way to understand key information such as price fluctuations, trading volume, and market value changes of various digital assets in real time.

CoinMarketCap contains tens of thousands of digital asset information, suitable for users who need macro data; 3.

Altcoins worth paying attention to in 2025 include Solana (SOL), Chainlink (LINK), Near Protocol (NEAR) and Arbitrum (ARB), which have advantages in transaction speed, cross-chain infrastructure, user-friendliness and the Layer 2 ecosystem, and can be obtained on mainstream platforms. 1. Solana has become the first choice for high-frequency applications with high TPS and low fees. Firedancer will enhance its performance when it launches; 2. Chainlink, as a key oracle project, plays an important role in RWA and cross-chain interoperability; 3. Near lowers the Web3 threshold through human readable accounts and AI strategies to promote

In cryptocurrency trading, stop loss and take profit are the core tools of risk control. 1. Stop loss is used to automatically sell when the price falls to the preset point to prevent the loss from expanding; 2. Take-profit is used to automatically sell when the price rises to the target point and lock in profits; 3. The stop loss can be set using the technical support level method, the fixed percentage method or the volatility reference method; 4. Setting the stop profit can be based on the risk-return ratio method or the key resistance level method; 5. Advanced skills include moving stop loss and batch take-profit to dynamically protect profits and balance risks, thereby achieving long-term and stable trading performance.
